In line with the ShadowRealm proposal changes in the WebIDL spec:
webidl#1437 and supporting changes in HTML spec.
This is required for ShadowRealms as they have no relevant settings
object on the shadow realm, so fixes a crash in the QueueingStrategy
test in this commit.
These interfaces are exposed on *, meaning it should work for workers
and our newly added shadow realm global object by being stored on the
universal global scope mixin.
This is required by mini Cloudflare invisible challenges, as it will
only run if the readyState is not "loading". If it is "loading", then
it waits for readystatechange to check that it's not "loading" anymore.
Initial about:blank iframes do not go through the full navigation and
thus don't go through HTMLParser::the_end, which sets the ready state
to something other than "loading". Therefore, the challenge would never
run, as readyState would never change.

`StyleComputer::font_matching_algorithm` was creating a copy of a
`FlyString` every time a `MatchingFontCandidate` was constructed or
copied, causing millions of unnecessairy reference updates when a
lot of fonts are loaded.
While a more permanent solution would be to not load so many unused
fonts, let's do the right thing and remove the unnecessairy copies of
`FlyString`.
CDATASection inherits from Text, and so it was incorrect for them to
claim not to be Text nodes.
This fixes at least two WPT subtests. :^)
It also exposed a bug in the DOM Parsing and Serialization spec,
where we're not told how to serialize CDATASection nodes.

Instead of checking the header in ZlibDecompressor::create(), we now
check it in read_some() when it is called for the first time. This
resolves a FIXME in the new DecompressionStream implementation.
Implemented by reusing AddMask display list item that was initially
added for `background-clip` property.

For a while we used the wider Paintable type for stacking context,
because it was allowed to be created by InlinePaintable and
PaintableBox. Now, when InlinePaintable type is gone, we can use more
specific PaintableBox type for a stacking context.
I believe this is an error in the UI Events spec, and it should be
updated to match the HTML spec (which uses WindowProxy everywhere).
This fixes a bunch of issues already covered by existing WPT tests.
Spec bug: https://github.com/w3c/uievents/issues/388
Note that WebKit has been using WindowProxy instead of Window in
UI Events IDL since 2018:

This change ensures that:
- if an element for which an accessible name otherwise wouldn’t be
computed is referenced in an aria-labelledby value, the accessible
name for the element will be computed as expected.
- if an element has both an aria-label value and also an
aria-labelledby value, the text from the aria-label value gets
included in the computation of the element’s accessible name.
Otherwise, without this change, some elements with aria-labelledby
values will unexpectedly end up without accessible names, and some
elements with aria-label values will unexpectedly not have that
aria-label value included in the element’s accessible name.
