These don't have to worry about the input not being valid UTF-8 and
so can be infallible (and can even return self if no changes needed.)
We use this instead of Infra::to_ascii_{upper,lower}_case in LibWeb.
- Include vertical border spacing in row group offset calculation so
that they are axis-aligned with child row/cell elements. This makes it
so there isn't horizontal and vertical overflow caused by child
row/cell elements.
- Include horizontal border spacing in tr width calculations. This makes
it so tr elements don't have overflow anymore when there are multiple
columns.
- Apply vertical caption offset to row group top offset.
- Don't double-count top padding when calculating vertical offset for
tr and row groups.
Instead of re-symbolicating entire stacks from scratch every time
we want a JS VM backtrace, we now use the ExecutionContext object as
cache storage via a new CachedSourceRange object.
This means that once a stack frame has been symbolicated, we don't
have to resymbolicate it again (unless the program counter moves
within that stack frame).
This drastically reduces time spent in symbolication in some WPT tests.
Cookies have a minimum expiry resolution of 1 second. So to test cookie
expiration, the test had to idle for at least a second, which is quite a
noticeable delay now that LibWeb tests are parallelized.
Instead, we can add an internal API to expire cookies with a time offset
to avoid this idle delay.
Useful for finding tests that take a long time to execute.

CSS Syntax 3 (https://drafts.csswg.org/css-syntax) has changed
significantly since we implemented it a couple of years ago. Just about
every parsing algorithm has been rewritten in terms of the new token
stream concept, and to support nested styles. As all of those
algorithms call into each other, this is an unfortunately chonky diff.
As part of this, the transitory types (Declaration, Function, AtRule...)
have been rewritten. That's both because we have new requirements of
what they should be and contain, and also because the spec asks us to
create and then gradually modify them in place, which is easier if they
are plain structs.
This is an ad-hoc change to account for the fact that we may run
arbitrary code while waiting for the tasks in this function to complete.
I don't have a way to reproduce it, but I've seen trouble caused by
navigables disappearing, which causes the history step numbers to be
disturbed.
Previously Selection.extend() used only the relative node order to decide which
direction to extend the selection. This leads to incorrect behaviour if
both the existing and new boundary points are within the same DOM node
and the selection direction is reversed.
This change fixes all the failing subtests in the WPT extend-* test
suites.
Loading Ladybird on Github results in 37 debug logs about being unable
to parse an empty Date string. This log is intended to catch Date
formats we do not support to detect web compatability problems, which
makes this case not particuarly useful to log.
Instead of trying to parse all of the different date formats and
logging that the string is not valid, let's just return NAN immediately.
This was previously negated due to a misread of
https://url.spec.whatwg.org/#concept-url-equals. This change fixes a
bunch of WPT crashes such as
"/html/browsers/history/the-history-interface/001".
