- Add support for `text-decoration-line: double`: Line drawing is done
similar to how it works in Firefox and Chromium. A gap of half of line
thickness is added between each line.
- Fix support for `text-decoration-line: wavy`: Wavy lines rectangles
were not calcualted properly, which meant they were rendered as solid
lines. Now the amplitude of the wave is 1.5 times line thickness.
Testing: A manual test is updated `tests/html/text_deco_simple.html`
to cover more cases. In general, rendering of text-decorations is
difficult
to test via reftesting.

Text decorations have a special kind of propagation. Instead of
propating these during box tree construction, move propagation to
stacking context tree construction. This will allow for using a very
easy type of incremental layout when text decorations change. For
instance, when a link changes color during hovering over it, we can skip
all of box and fragment tree construction.
In addition, propagation works a bit better now and color and style
properly move down from their originating `Fragment`s.
This introduces three new failures, because now we are drawing the
text-decoration with the correct color in more places, which exposes an
issue we have with text-decorations not being drawn in relation to the
baseline (taking into account `vertical-align`).
Testing: There are tests for these changes.
Fixes#31736.

This way, we don't always set the destination to Document (which is as
the spec is written today). Instead, we set it it in the load_data,
depending on which context we load it from.
Doing so allows us to set the `Destination::IFrame` for navigations in
iframes, enabling all frame-related CSP checks.
While we currently block iframes when `frame-src` or `child-src` is set,
their respective tests don't pass yet. That's because we don't yet
handle the cases
where we fire the correct `load` event.
Also update one WPT test to correctly fail, rather than erroring. That's
because it was using the wrong JS test variable.

This change adds a shadow-tree widget for `<input type=color>` elements.
It also involves some changes to the way layout interacts with the DOM,
because currently all `input` and `textarea` elements are rendered as
plain text and their descendants are ignored. This obviously doesn't
work for `<input type={color, date, range, etc}>`.
<details><summary>HTML used for the screenshot above</summary>
```html
<input type=color>
```
</details>
Testing: I doubt that this affects WPT tests, because the appearance and
behaviour of the widget is almost entirely unspecified.

Intrinsic sizing keywords weren't working correctly on the min and max
block sizes of a flex container, because we weren't setting the
`CacheableLayoutResult::content_block_size` to the right value. This

container.

`TextRun`s use their parent style to render. Previously, these styles
were cloned and stored directly in the box tree `TextRun` and resulting
`TextFragment`s. This presents a problem for incremental layout.
Wrapping the style in another layer of shared ownership and mutability
will allow updating all `TextFragment`s during repaint-only incremental
layout by simply updating the box tree styles of the original text
parents.
This adds a new set of borrows when accessing text styles, but also
makes it so that during box tree block construction
`InlineFormattingContext`s are created lazily and now
`InlineFormattingContextBuilder::finish` consumes the builder, making
the API make a bit more sense. This should also improve performance of
box tree block construction slightly.
Testing: This should not change observable behavior and thus is covered
by existing WPT tests.

To be able to abort the update, extract the functionality into a
separate method. Otherwise, we don't run the `node.rev_version` at the
end, which according to the comment is probably important.
Not all `style-src` tests pass and I don't fully understand why yet, but
I presume it has to do with some special quirks of stylesheets that
other CSP checks don't have. All `style-src-attr-elem` tests pass
though.

Instead of resolving the canvas background properties (essentially
keeping a possible reference to the `<body>`'s style) during fragment
tree construction, wait until painting to possibly find the style on an
appropriate `<body>` fragment. This is possible now because `Fragment`
keeps a list of flags with relevant information about the root and
`<body>` elements.
A benefit of this approach is that styles aren't cached in the fragment
tree, which would be problematic for incremental layout. In addition,
the old code was making an effort to transform the `<body>`'s background
by the root element's transform. Only Safari does this and there was
a resolution the WG that this should not happen in
https://github.com/w3c/csswg-drafts/issues/6683.
