This fixes the failures in bug 1671573 and just works thanks to the
invalidation improvements I did for :is / :where.
Added a couple tests for invalidation which is the tricky bit. 001 is a
very straight-forward test, 002 is the :is test but with :is() replaced
by double-:not().
This also fixes default namespaces inside :is() / :where(), which are
supposed to get ignored, but aren't. Added tests for that and for the
pre-existing :not() behavior which Chrome doesn't quite get right.

Adjust is-where-parsing.html to work with both the new and old behavior,
and add a test for the new behavior.
Depends on D90049

This is strictly better and more flexible, but can change specificity so
have a pref in case it causes trouble. I doubt it will though, the
specificity rules of :is() make more sense, and my gut feeling is that
:-moz-any is not very used on the wild.
Make it early-beta-or-earlier for now to minimize risk, once this is on
nightly for a bit we can enable it everywhere.

I also update the wpt becasue it seems the original one lets <ratio>
support the addition. However, the spec says "Addition of <ratio>s is not
possible".

And alias :-moz-ui-valid and :-moz-ui-invalid to them.
There are CSSWG resolutions for these for quite a while, and spec for
user-invalid.

No other browser supports anything like this and we don't even have
internal users. Only uses of this I've found on the wild were just
resetting the box shadow internal styling we added in bug 582277 (and
since removed in bug 600151).

This reduces the amount of assembly instructions generated by this
function from 18k+ to ~800.
This should make reasoning about its stack space usage sane, and should
fix the ASAN stack overflows, but also we should take this regardless,
because it's saner and makes reading it simpler.
I also think that the writing_mode shenanigans is fixing a bug (I think
before this, we'd pick the first physical value which mapped to any of
the properties, which is wrong), but I haven't bothered looking for a
test-case that fails before my patch. The relevant WPTs
(css/css-logical/animation*) still pass.

This brings the time down to 1.6ms from 4.8ms on the test-case in the
bug. This should be improvable too, but I think this is a nice
improvement for regular styling as well.

This doesn't use a full bitmap for every single rule type, as we only expect
that keyframe, page, and style rules will be checked.

Actually, there's not so much we can improve right now, in the sense
that:
* We need the ::-moz-page-content pseudo-element to be able to set
`display` on the page, since that's a style rule rather than a @page
rule. We could get away without it.
* Keeping the current code-path (slightly cleaned up) is less code, for
now at least. We can have a separate code-path or what not that
actually performs the @page rule selector-matching and what not if
needed when we get to named pages or other page selectors. Selectors
like :first should be pretty trivial to implement, actually.
We make some paged mode anon boxes non-inheriting anon boxes. This
allows us to share the styles and is generally nicer. They don't need to
inherit from anywhere.
We could remove the origin handling and don't look at UA rules or what
not, but it seems pretty harmless to do that.
We also fix the name of the pseudo-elements to match the capitalization.

Some GTK themes use very soft colors for selection backgrounds, using
darker colors for the text. This makes the tab and focus outlines in the
tab bar not have sufficient contrast with usual backgrounds.
I needed to do this for bug 1690778, but it seems worth doing it on the
front-end as well.

It's only used to disambiguate between the one-argument and the trait
version of Keyword::parse. Instead, just explicitly use the trait
version, so that we don't need to specify it.

This shipped in 85, we can remove the feature flag now. Keep
:-moz-focusring as an alias to :focus-visible at parse time.

There's no reason we should need an scrollbar box to query the size of a
scrollbar. I plan to use this in the following patch to make the size of a
resizer not vary depending on whether the container has scrollbars or not,
which is what ultimately causes the reftest failure.
