b376ab4e81 LibWeb/CSS: Serialize Supports::Declaration as original representation
Fixes some WPT tests that expected `supports(foo:bar)` to serialize as
`supports(foo:bar)`, instead of `supports(foo: bar)` with a space
between.

Reading the original_full_text directly also lets us delete
Declaration::to_string(), which was only used here.

4ed1c56267 LibWeb/CSS: Parse all supports features in @import supports()
The previous implementation assumed that the contents of `supports()`
was either a raw declaration, or a block containing some number of them.
This meant we wouldn't parse things like `supports(not (a:b))` or
`supports(selector(*))`.

`parse_a_supports()` actually does what we want in every case except for
raw declarations (`supports(a: b)`), so let's always call it first, and
then fall back to parsing a single declaration.

d9abfdf2ab LibWeb/CSS: Allow non-StyleValueLists in animation properties
Reverts 51f694c6af and
b52beb5105.

The animation-* properties are in an awkward place currently, where
they *should* be lists, and a lot of our code acts as if they are, but
actually we parse them as single values. The above commits caused a few
WPT tests to crash - see link below. I've imported one of them to
prevent future regressions.

e5ea4f9bdf LibWeb/HTML: Add source field to ToggleEventInit
Corresponds to:

As we now have a field in that dictionary, I removed the separate
`source` parameter from ToggleEvent::create(). Also updated the
relevant test.

f81bb1bd8c LibWeb/CSS: Absolutize GradientStyleValues
This lets us not care about non-absolute Length units when resolving
gradient data, as they'll already have been converted to px.

We can also use Angle::from_style_value() safely on absolutized angles,
which reduces some boilerplate code.

e8ba1b4fdf LibWeb: Simplify serialization of coordinating value list shorthands
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

5371862d11 LibWeb: Use correct play state for handling animations on display change
Previously we were doing a couple things wrong:

 - Only supporting the case where we had one animation-play-state

cbfae97101 LibWeb: Include empty header values when joining duplicated headers
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.

1f5ffe04c8 LibWeb: Fix race condition between read_all_bytes and stream population
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.

50a79c6af8 LibWeb: Change SessionHistoryTraversalQueue to use Promises
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.

aac387bcc6 LibWeb/DOM: Copy "allow declarative shadow roots" to template document
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.

b2b889e1da LibWeb: Ensure registered transitions are reflective of properties
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.

6e17503423 LibWeb: Add and remove MutationObservers at specified times
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.
