Extend character-based soft wrap prevention to before atomics (#30800)
The changes in #30740, fixed an issue where certain characters should
prevent line break opportunity after atomics. This change extends that
to also apply to before atomics, which is what the specification says
should happen.

Stop sending " " to linebreaker for replaced content (#30740)
We previously sent a " " to the linebreaker in order to ensure that the
next text had a soft wrap opportunity at the start. Calling `next(" ")`
without waiting until the returned index was 1, violated some
invariants of linebreaker ultimately causing a panic.

Instead of using the linebreaker for this, simply keep a flag in the
IFC layout state, which avoids the problem entirely.

Fixes #30703.

Add initial support for sticky positioning for non-legacy layout (#30686)
* Add initial support for sticky positioning for non-legacy layout

Many tests still fail for a variety of reasons. One of the primary ones
is that CSSOM currently does not return correct values for elements
positioned by sticky nodes. This requires changes to WebRender to work
properly.

* Fix an assertion failure in the legacy layout sticky code

Fix transform assertion failures in Layout 2013 and Layout 2020 (#30713)

This change stops their creation at an earlier stage.

f4d3af296c Move *_traits and other shared types to shared
This is the start of the organization of types that are in their own
crates in order to break dependency cycles between other crates. The
idea here is that putting these packages into their own directory is the
first step toward cleaning them up. They have grown organically and it
is difficult to explain to new folks where to put new shared types. Many
of these crates contain more than traits or don't contain traits at all.

Notably, `script_traits` isn't touched because it is vendored from
Gecko. Eventually this will move to `third_party`.

Add better support for line breaking across inline box boundaries (#30628)
Earlier versions of inline layout in the new layout system did not
properly support line breaking when unbreakable segments spanned
multiple inline boxes. This change updates inline layout to add support
for that. Now items are added to an unbreakable segment before being
committed to a line.

Make LineItems a token stream on the root (#30608)
Flattening the LineItem tree into a token stream will allow for handling
the case where an unbreakable line segment spans multiple inline boxes
which might have different hierarchies. This change also fixes the

Consider trailing_whitespace_advance when calling place_line_among_floats() (#30586)
After placing a float, FloatBox's layout_into_line_items() was calling
place_line_among_floats() with ifc.current_line.inline_position as the
width of needed by the contents of the line.

The problem is that this amount includes the trailing whitespace advance
and thus it could seem that the in-flow contents wouldn't fit next to
the float.

That's not the case, since collapsible whitespace at the end of the line
is removed, and preserved whitespace hangs.

So this patch subtracts ifc.current_line.trailing_whitespace_advance
when calling place_line_among_floats(), like it was already happening
when computing the available_inline_size.

Anonymous boxes that wrap inlines should not inherit overflow (#30579)
In legacy layout, anonymous text wrappers were inheriting the `overflow`
and `text-overflow` properties. This results in the creation of extra
clipping for these anonymous wrappers which could clip away floats. We
will likely implement `text-overflow` differently in non-legacy layout.

This change marks all legacy layout pseudo elements as "legacy" and also
adds a new pseudo element for non-legacy layout that does not inherit
`overflow`.

Fixes #30562.

Improve line box block size calculation (#30519)
Improve the calculation of the block size of line boxes and all their
component elements. Even empty spans can increase the size of the line
based on their font-size. Elements that have a line-height should
increase the block size of the line, but that setting should not effect
their own size.

In addition to the new passes there are some new failures

Failing because a progression exposes the real issue these tests are
testing:

Allow raising FloatContext ceiling after processing box with overflow (#30539)
When a box has overflow, any floats placed in that box will lower the
float ceiling into the overflow. If no float is placed in the box
though, the ceiling should be the block position where the overflow
starts. We already know where this is, because we might be passing a
negative value for the new block position after processing a box
(content_size - actual_size would be negative). This negative value
never raises the ceiling though since a maximum is used.

In the case that there is overflow, this change allows raising the
ceiling, but never passed the lowest float. This necessitates keeping
two values for the ceiling: one for floats and one for non-floats.

Fixes #30304.

Only access hit test items for the current epoch in the compositor (#30491)
When display lists update quickly, a hit test result might be returned
for a previous display list / list of hit test items. When that happens,
ignore the hit test result.

This fixes a crash, but there might be situations where we can do
something better, such as wait for display list processing to finish
before performing the hit test. A future change might do this for events
like mouse clicks and touch events that should never be thrown away.
Ultimately, the best thing is likely moving hit testing back to layout
or script so a valid hit test can always be performed against the
current DOM.

Refactor scrolls on the window object (#29680)
Refactor the scrolling and scrollable area calculation on the window
object, to make it better match the specification. This has some mild
changes to behavior, but in general things work the same as they did
before. This is mainly preparation for properly handling viewport
propagation of the `overflow` property but seems to fix a few issues as
well.

There is one new failure in Layout 2020 regarding `position: sticky`,
but this isn't a big deal because there is no support for `position:
sticky` in Layout 2020 yet.

Refactor inline layout nesting (#30289)
This makes the nesting architecture of inline layout a lot simpler. Now
PartialInlineBoxFragment and InlineNestingLevelState are replaced by
two structs:

 - InlineContainerState
 - InlineBoxContainerState

InlineContainerState holds state for the root of the inline formatting
context, while InlineBoxContainerState holds state for inline boxes.
InlineBoxContainerState has an InlineContainerState as the first
element, thus "extends" it.

Now the inline iterators are stack variables directly in the `layout()`
method. They are no longer stored in the state. This avoids the weird
nesting of state and instead relies on a normal vector to hold the
stack of state.

Avoid crash in PlacementAmongFloats (#30235)
PlacementAmongFloats was assuming that there would always be a FloatBand
at a position smaller than or equal to the given ceiling, but this was
not the case for negative ceilings.

The reason is that the FloatContext initialized the FloatBandTree with
a band at 0, and another at +∞.

This patch changes the initial bands to −∞ and +∞. This seems more
consistent and matches the expectation of PlacementAmongFloats.

Layout floats as children of their inline ancestors (#30130)
When layout was split into two phases, floats were laid out as direct
children of the inline formatting context. This meant that they were
positioned properly, but not properly made children of their inline
ancestors' stacking contexts. This change maintains the proper
positioning of floats, but positions them relatively to their inline
ancestors.

The big change here is that `text-align` needs to be taken into account
before actually laying out LineItems. This has the added benefit of
setting inline layout for the implementation of `text-align: full`. Now
all line items are laid out at the real final position and we can adjust
the `start_corner` property of float `BoxFragments` when their ancestors
are laid out.

We keep getting this pattern of properties that have a set of joint and

container-type is one such type, and I think we should have a single way
of dealing with this, thus implement deriving for various traits for
bitflags, with an attribute that says which flags are single vs mixed.

See docs and properties I ported. The remaining ones I left TODOs with,
they are a bit trickier but can be ported with some care.

* Further changes required by Servo

* style: Implement parsing / serialization for container{,-type,-name} CSS properties

Two noteworthy details that may seem random otherwise:

 * Moving values around in nsStyleDisplay is needed so that the struct
   remains under the size limit that we have to avoid jumping allocator
   buckets.

 * All the test expectation churn is because tests depend on
   `container-type: size` parsing to run, and now they run. Tests for
   the relevant bits I implemented are passing, with the only exception
   of some `container-name-computed.html` failures which are
   https://github.com/w3c/csswg-drafts/issues/7181. Safari agrees with
   us there.

Other notes when looking at the spec and seeing how it matches the
implementation:

 * `container` syntax doesn't match spec, but matches tests and sanity:
   https://github.com/w3c/csswg-drafts/issues/7180

 * `container-type` syntax doesn't _quite_ match spec, but matches tests
   and I think it's a spec bug since the definition for the missing

This allows popups and sidebars to use the chrome preferred

We still return the PreferredColorSchemeForContent() when there's no
pres context (e.g., for display:none in-process iframes). We could
potentially move a bunch of the pres-context data to the document
instead, but that should be acceptable IMO as for general web content
there's no behavior change in any case.

This makes the worst case for cascade performance slightly more

rare.

This needs a test, but needs to wait until the writing-mode dependent

Before bug 1763750, we unconditionally called compute_writing_mode,

However after that bug we only do that if we apply any
writing-mode-related property.

We could just call compute_writing_mode unconditionally, but instead it
seems better to skip all that work for visited cascade and reuse the
mechanism introduced in that bug to only apply the visited-dependent
longhands.

We assert that all visited-dependent longhands are "late" longhands, so
as to also avoid applying the font group and such.

This has no behavior change right now, but will simplify sharing code
with container queries.

Container queries will have container information in the
computed::Context (this is necessary anyways for container-based units),
so this avoids having to have different code for media and container
queries.

* Further changes required by Servo

* style: Add scroll() to animation-timeline for style system

scroll() is defined in the spec proposal, and there is a temporary spec:
https://drafts.csswg.org/scroll-animations-1/rewrite#scroll-notation.

The spec is still under development, so we don't drop the orignal
scroll-timeline at rule. Instead, we add a new scroll() notation to
animation-timeline, and support both syntax for now.

* style: Tweak contain bitflag definition order to avoid static constructors

This has no behavior change otherwise. The STRICT definition depended on
SIZE, which was defined later. That's fine in Rust, but in C++ it causes
the initialization to be dynamic because it doesn't have the definition
of SIZE yet (ugh).

This is the fix for the regression, though the following patch turns on
constexpr support in cbindgen, which would've caught this at build-time,
and guarantees that we don't have extra static constructors.

* style: Move some of the media query code to a more generic queries module

No behavior change, just moving and renaming files.

The code in the "queries" module will be shared between @media and
@container.

@media has some other code that container queries doesn't need like
MediaList / MediaType / etc. That remains in the media_queries module.

* style: cleanup animation-name

Make the representation the same between Gecko and Servo code. This will
enable further clean-ups in the future.

Make serialization be correct, serializing as identifier unless it's an
invalid one (in which case we serialize as a string).

This changes our stringification behavior in the specified style, but
now it will match the computed style and be more correct over-all.

cross-fade() was kinda doing this in its own way with PercentOrNone, but
since now we have more use-cases for this we should probably make this a

let me know if you want them gone.

always rescue this from hg history if needed.

* style: Simplify selector flags setup even more

In my investigation for bug 1766439, I am digging into why selector
matching regressed.

It doesn't help that the selector-matching code is instantiated a
gazillion times (so there's a ton of copies of the relevant functions).

This was needed in the past because we had different ways of setting the
selector flags on elements, but I unified that recently and now we only
need to either set them or not. That is the kind of thing that
MatchingContext is really good for, so pass that instead on
MatchingContext creation.

* style: Track @container condition id in style rules

Much like we track layer rules. Consolidate that "containing rule state
we pass down while building the cascade data" in a single struct that we
can easily restore.

For now, do nothing with it. I want to land this patch separately
because it touches the Rule struct and CascadeData rebuilds, which both
are performance sensitive.

Its layout shouldn't change because I also changed LayerId to be a u16
(this shouldn't matter in practice, since LayerOrder is already a u16).

* style: Clean up unused -moz-window-shadow values

After bug 1768278 and bug 1767815 there's no more uses of the cliprounded value
in the tree (also it causes artifacts on HiDPI screens so we probably don't
want new usages).

The "sheet" value is unused, and the other values other than "default" and
"none" are only derived from "default", so they don't need to be exposed in the
style system.

Differential Revision: https://phabricator.services.mozilla.com/D145821

* style: More container queries plumbing

Provide container information in computed::Context and use it to resolve
the container queries.

This still fails a lot of tests because we are not ensuring that layout
is up-to-date when we style the container descendants, but that's
expected.

For now, don't turn it on by default yet, because I want to wait for

so on. But I think the code is simple enough to land this.

* style: Cache computed styles objects display: none subtrees

This reuses our existing undisplayed style generation, but in a
per-document rather than per-nsComputedDOMStyle object, which means that
we can avoid re-resolving styles of elements in display: none subtrees
much more often.

This brings the test-case in the bug to par with other browsers or
better, and is much simpler than the initial approach I tried back in
the day.

Split line layout into two phases (#30089)
In the first phase, we gather LineItems and then when we have enough to
form a line we turn them into Fragments. This will make it possible to
more simply implement `vertical-align` and `text-align: justify` because
we need to measure the different aspects of the candidate line and then
produce a Fragments.

This is a general refactor of the way that inline layout works, so comes
with some progressions. In addition there are some new failures.

New failures:

Some tests are now failing because only the test or reference is getting
proper line height when it wasn't before. These should be fixed in a
followup change that properly calculate line-height in more cases:

 - /_mozilla/css/list_style_position_a.html
 - /css/CSS2/floats/float-no-content-beside-001.html
 - /css/css-content/pseudo-element-inline-box.html
 - /css/css-flexbox/flexbox_flex-none-wrappable-content.html

Some tests are now failing because floats are now placed properly, but
are no longer in their inline box stacking contexts. These will be fixed
by a followup change which properly parents them:

- /css/filter-effects/filtered-inline-applies-to-float.html.ini
- /css/css-color/inline-opacity-float-child.html.ini

One test is failing due to floating point precision errors:

- /css/CSS2/floats-clear/floats-141.xht.ini

Avoid bad calls to solve_containing_block_padding_border_and_margin_for_in_flow_box (#30073)
Avoid solve_containing_block_padding_border_and_margin_for_in_flow_box()
for a block-level box that establishes an independent formatting context
(or is replaced) in the presence of floats, since the margins and inline
size could then be incorrect.

No actual change in behavior: this patch still resolves the margins
incorrectly with solve_block_margins_for_in_flow_block_level(),
and also keeps the old logic for width:auto.

However, this refactoring prepares the terrain to address these issues
in #30072 and #30057.

- Make current_bands_height() work when current_bands is empty.
- Add add_one_band() helper method.

Never resolve margin-left:auto to a negative amount (#30065)
With direction:ltr (and we don't support direction:rtl yet), the rules
from https://drafts.csswg.org/css2/#blockwidth imply that margin-left
shouldn't resolve auto to a negative amount.

This aligns Servo with Gecko and Blink. WebKit may resolve to a negative
amount in some cases.
