We know that longhand values are always `StyleValueList`s
Introduces a new fail in the `view-timeline-shorthand.html` WPT test
but this is because the test is incorrect and we now correctly don't
contract when `view-timeline-inset` has dissimilar cardinality. See
web-platform-tests/wpt#56181
Previously we were doing a couple things wrong:
- Using the cascaded rather than computed value (so we didn't support
CSS-wide keywords)
- Only supporting the case where we had one animation-play-state
The remaining failing tests in view-timeline-shorthand.html are due to
either:
a) incorrect tests, see web-platform-tests/wpt#56181 or;
b) a wider issue where we collapse coordinating value list longhand
properties to a single value when we shouldn't.

Fixes a regression from commit:
f675cfe90f
It is not sufficient to only check if the builder is empty, as we will
then drop empty header values (when the first found value is empty).
This is tested in WPT by /cors/origin.htm, but that requires an HTTP
server.
There might be a race between read_all_bytes and stream population.
If document load reads stream before it is populated, the stream will
be empty and might lead to hang in SessionHistoryTraversalQueue which
is expecting a promise to be resolved on document load.
This race can occur when stream population and document source are set
very close to each other. For example, when a newly generated blob is
set as the source of an iframe.
- navigation/multiple-navigable-cross-document-navigation.html has been
modified to trigger this race.
If multiple cross-document navigations are queued on
SessionHistoryTraversalQueue, running the next entry before the current
document load is finished may result in a deadlock. If the new document
has a navigable element of its own, it will append steps to SHTQ and
hang in nested spin_until.
This change uses promises to ensure that the current document loads
before the next entry is executed.
Fixes timeouts in the imported tests.

This flag defaults to false for new Documents, such as the one created
here for use by template elements' contents. Without setting it to
true, nothing inside a template can have a declarative shadow dom.
As noted, this appears to be a spec issue. I am not convinced that this
is the correct fix, but it is simple and does solve the issue without
any apparent regressions.
This would happen for example when removing a slot element from the DOM,
in which case it would keep its old list of assigned slottables even
though it now has none. Fixes a couple of WPT tests.
We don't discern between opaque and non-opaque alpha types in LibGfx,
which at some point we might need to do. But for now, assume all opaque
Skia surfaces have premultiplied alpha.
Fixes#6892.
Fixes the `dom/nodes/getElementsByClassName-11.xml` WPT test, which can
be imported but unfortunately not run since it's not an .html file.

Previously we would only update these if:
a) We had a cascaded value for `transition-property`
b) The source of that cascaded value had changed since we last
registered transitions
This meant that there were a lot of changes we didn't apply:
- Changes exclusively to properties other than `transition-property`
(e.g. `transition-duration`, `transition-behavior`, etc)
- Removing the `transition-property` property
- Updating the `transition-property` property in a way that didn't
change it's source (e.g. setting it within inline-style)
Unfortunately this does mean that we now register transitions for all
properties on most elements since "all" is the initial value for
"transition-property" which isn't great for performance, but that can be
looked at in later commits.
Also renames the `clear_transitions` function to clarify this doesn't
affect the associated transition animations.
This fixes an issue where transitions weren't being cancelled when the
relevant transition-property entry was no longer present
We use a Vector for this, but its spec definition is an ordered set.
That means we need to ensure we don't add duplicates. This fixes issues
where we would send slotchange events multiple times to the same
HTMLSlotElement.
In the current spec, MutationObservers are explicitly added to the
pending mutation observers list, and they are removed when that list is
cleared in the "notify mutation observers" microtask.
This solves some issues with slotchange events.
As noted, we delay actually emptying the list of pending mutation
observers until after we're finished with the "clone", because we can't
actually copy or move the intrusive list. As far as I am aware, this
should not affect behaviour because only one microtask can run at once.
Adds a stub that returns a cached rejected promise with a
not yet implemented error. This converts
battery-status/battery-promise-window.https.html from timeout
to pass. Full implementation still needed.
Previously, we only supported very basic numbers and a single level of
text positioning support in the `x`, `y`, `dx` and `dy` attributes in
`<text>` and `<tspan>` SVG elements.
This improves our support for them in the following ways:
* Any `length-percentage` or `number` type value is accepted;
* Nested `<text>` and `<tspan>` use the 'current text position'
concept to determine where the next text run should go;
* We expose the attributes' values through the API.
Though we still do not support:
* Applying the `rotate` attribute;
* Applying transformations on a per-character basis.
* Proper horizontal and vertical glyph advancing (we just use the path
bounding box for now).
This changes `link-element-rel-preload-load-event.html`, so the test no
longer depends on the relative ordering of load and error events.
This is required for the upcoming change that makes fetching unbuffered
by default, as the test would otherwise become flaky.
`font-weight` and `font-size` both can have keywords that are relative
to their inherited value, and so need recomputing when that changes.
Fixes all but one subtest in font-weight-computed.html, because that
remaining one uses container-query units. No font-size tests seem to be
affected: font-size-computed.html doesn't update the parent element's
`font-size` so this invalidation bug didn't apply.
Our HTTP disk cache is currently manually tested against various sites.
This patch adds some tests to cover various scenarios, including non-
cacheable responses, expired responses, and revalidation.
In order to ensure we hit the disk cache in RequestServer, we must
disable the in-memory cache in WebContent.
