I haven't spotted any UI regression from this, and this should generally
make the XUL -> modern flex transition easier, and simplify some
of the relevant code.
This does fix a few layout issues with emulated flexbox.
For the most part, this shouldn't change behavior without that. This
changes behavior if you have mixed inline/non-inline content in the same
XUL box (before they'd get a single item, now you'd get the flexbox /
grid behavior of one item per inline run), and multiple inline-elements
(which would become their own flex items). But I pushed a patch with
some asserts and they didn't fire on our browser mochitests, so I think
we're good.
The UA rule refactoring (removing the inherit from xul anon blocks)
shouldn't matter in practice, since we only have one item (so
box-ordinal is irrelevant) and they have overflow: visible (so
text-overflow and overflow-clip-box shouldn't have an effect).

It's always true, so remove it.
Add another pref to allow -webkit-line-clamp to work on all blocks
rather than just legacy -webkit-boxes, which seems something we should
try to look into, eventually.

This is a hack, sorta, similar to Chromium's:
https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/core/layout/layout_object.cc;l=356;drc=312b74e385e6aba98ab31fd911238c0dc16b396c
except at computed-value rather than used-value time, because it's both
simpler to reason about and prevents lying in the computed style.
This fixes the relevant test-case, and matches closer what Chromium does,
by not creating anonymous flex items for all elements inside the
line-clamp context.
The behavior change is covered by the test changes. I had to also fix a
couple pre-existing bugs that were caught by tests, now that the
line-clamped block is the -webkit-box-styled element rather than an anonymous
flex item (and thus now had padding).

In the past, mathvariant was cancelling the effect of legacy
fontstyle/fontweight attributes by resetting the font-style/font-weight
properties. These legacy attributes have been removed in bug 1783841,
so remove this hack from Stylo and add corresponding WPT test.

The math-depth implementation is refined to take into account the
ScriptPercentScaleDown and ScriptScriptPercentScaleDown constants (if the
parent's first valid font has a MATH table) in order to calculate the
scale factor between math-deth 0 and 1, and between 0 and 2 respectively.
Behavior is unchanged if the legacy scriptsizemultiplier attribute is
specified or if no MATH table is available.
The preference layout.css.math-depth.enabled remains disabled in nightly
until the remaining bit (support for font-size: math) is implemented in
bug 1667090.

They are not transitionable:
https://drafts.csswg.org/css-transitions-1/#transitionable
There are some new failures in background-image-interpolation.html,
but I think the test is wrong, because it expects background-image
to be transitionable, even though the spec defines it with a discrete
animation type.
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.

If Servo-specific `style` changes will need to be upstreamed anyway, I might as well fix a thing that had thrown me off!

These are gated by the same layout.css.font-tech.enabled pref as the

There are a couple of current issues/discussions that may lead to a change in the set of supported keywords, so we may want to hold back a little on actually shipping this.
- In https://github.com/w3c/IFT/pull/113, the WebFonts WG proposes several new incremental-* keywords (and maybe implies dropping the currently-defined incremental?)
- In https://github.com/w3c/csswg-drafts/issues/7633, I just proposed renaming the feature-* keywords to features-* (plural) for better readability; I'd like to see a decision on that before we ship this to release.

Not sure I caught all, but normalizing to 0 was already our existing
behavior. This feature needs more work before it can be enabled more
generally, so make it nightly-only, for now.
Also, it's unclear per spec what the serialization for infinity*1s or so
should be. Right now we serialize to <very-big-number>s, which seems
reasonable, but some tests (but not others!) expect different behavior.
I left those untouched for now.

We now have test coverage, so let's do this.
The remaining failures are just about infinity/nan, which is a

This aligns with CSS Fonts 4 (rather than Fonts 3) and with behavior in other browsers;
I don't expect any significant breakage, given that specifying multiple format strings
was never supported in other engines AFAIK, and never served any useful purpose.

This matches what Linux and macOS do, and that allows the fix for bug 1782623
to work on Windows for unstyled selects.
This also simplifies the CSS (though it adds a new system color which is a bit
more annoying). I filed https://github.com/w3c/csswg-drafts/issues/7561 to
propose adding a more generic way to do this in the future (not just for
Firefox).

When something switches to display: none, right now we rely on
StopAnimationsForElementsWithoutFrames(), which posts a restyle and the
previous ProcessPendingRestyles call was papering over it.
For other elements in the display none subtree it doesn't matter,
because we don't keep their styles around, but for the display: none
element themselves we do need to update transitions on time.
We could, possibly more generally, remove
StopAnimationsForElementsWithoutFrames() altogether and cancel
animations when we clear style data, perhaps... But that's probably
worth a follow-up.

Even we don't have internal aliases right now (and that seems a bit
silly) we do have pref-gated aliases. An alias ID passed to IsEnabled
with the wrong EnabledState would misbehave, assert, and crash.
Though we don't have such callers in the tree because InspectorUtils
passes only arguments that make us not look at the flags, it seems more
reliable this way.

So we can specify the keyframe-specific composite operation. However,
these is a spec issue about the default composite for CSS Animations:
https://github.com/w3c/csswg-drafts/issues/7476.
I choose to use auto as the default composite for missing keyframes to match
the definition in web-animations-1 because I think this makes more sense:
> If the keyframe-specific composite operation for a keyframe is not set, the
> composite operation specified for the keyframe effect as a whole is used for
> values specified in that keyframe.

This patch introduces animation-composition longhand but we don't
accept it in @keyframe rule for now. I will support this for @keyframe
in the patch series.
Besides, the shorthand of animation doesn't include animation-composition.
The spec issue is: https://github.com/w3c/csswg-drafts/issues/6946.
We could fix the shorthand once this spec issue gets updated.
