WPT tests are expected to create screenshots as soon as everything is
loaded. If an animation is happening adding the "reftest-wait" class to
the root element is appropriate way to delay the screenshot. Previously,
the
test harness was waiting for all animations to finish, but that is just
leading to many timeouts. Removing that code fixes the timeouts.
Two Servo-specific tests are also updated as they were written with
Servo's previous behavior in mind.
Testing: There are test result updates for this change. Many TIMEOUTS
now either correctly
PASS OR FAIL.
Fixes: #36931.

Testing: No tests, if `test-wpt` broke again then we would notice pretty
quickly.

This change adds support for the `::marker` pseudo-element and ensure
that
markers are cached into the box tree. This is only initial support,
there are a few
things missing such as animations, transitions, and support the
`content` CSS
property.
Testing: There are WPT tests for this change.

This patch implements the `FontFace` interface, but with some caveats
1. The interface is only exposed on `Window`. Support for Workers will
be handled in the future.
2. The concept of `css-connected` `FontFace` is not implemented, so
`@font-face` rules in stylesheets will not be represented in the DOM.
3. The constructor only supports using `url()` strings as source
and `ArrayBuffer` and `ArrayBufferView` are not supported yet.
A skeleton implementation of the `load` method of `FontFaceSet` is also
implemented in this patch. The intention is to support some web pages
that don't load without this method.

layout: Basic implementation of size keywords on `flex-basis`
This splits the logic to resolve the used value of `flex-basis` into its
own method, which preserves size keywords.
And then it changes `flex_base_size()` to resolve the provided keywords
properly. However, it doesn't handle size keywords in the cross axis.

Post layout, when a `Window` has all of the new `<iframe>` sizes, size
any `Window`s for `Pipeline`s in the same `ScriptThread` synchronously.
This ensures that when laying out from the outermost frame to the
innermost frames, the frames sizes are set properly.
There is still an issue where a non-same-`ScriptThread` `<iframe>` sits
in between two `<iframe>`s of the same origin. According to the
specification these frames should all be synchrnously laid out --
something quite difficult in Servo. This is issue #34655.
This is the first change in a series of changes to improve the
consistency of `<iframe>` loading and sizing.

This test manually animates the height of an `<iframe>` that has content
which uses the `vh` unit. Each tick of the animation changes the height
by one pixel. Inside the `<iframe>` the element using `vh` units has a
transition applied, so every manual tick of the animation triggers a new
transition. The causes a pretty slow test execution.
This change improves `vh_not_refreshing_on_chrome.html` to remove
flakiness by making the test wait to start until after the `<iframe>` has
loaded and to increase the `<iframe>` height by 10 pixels instead of 1
when doing the manual animation. These changes make the test faster and
much less flaky in Servo.
In addition, the test is reformated a bit removing extraneous whitespace
and renamed to follow WPT naming conventions.
Fixes#23385.
Fixes#15570.

Adds support for min-content, max-content, fit-content and stretch,
for block-level elements that don't establish an independent formatting
context, and for block-level elements when there is no float.

The spec says that cyclic percentages in min sizing properties should
be resolved against zero when computing intrinsic contributions.
We were already doing that in the inline axis, but we were treating
the entire expression as `auto` in the block axis.
With this patch we will follow the spec in both axes. But note that
browsers don't follo the spec in either axis, so we may have to revisit
(see https://github.com/w3c/csswg-drafts/issues/10969).
calc-min-height-block-1.html now fails because it tests what browsers
do instead of what the spec says.

For the sizing properties.
We don't actually support them yet, just treating them as
the initial value.
