74c803c87b LibWeb: Ensure |= value selector handles multiple segments correctly
Previously, the `|=` would not compare strings containing `-`
characters correctly because it would only compare the element
attribute up to the first `-` character.

9973b01848 LibWeb/CSS: Improved implementation of background-blend-mode
This is a improved version of a73cd88f0c
The old commit was reverted in 552dd18696

The new version only paints an element into a new layer if background
blend modes other than normal are used. The rasterization performance
of most websites should therefore not suffer.

552dd18696 Revert "LibWeb/CSS: Implement 'background-blend-mode'"
This reverts commit a73cd88f0c.

Emitting SaveLayer for each paintable made rasterization a lot slower
on every website because now Skia has to allocate enormous amounts of
temporary surfaces. Let's revert it for now and figure how to implement
it with less aggressive SaveLayer usage.

9e65291ebd LibWeb/CSS: Discard unsupported style properties on pseudo-elements
Quite simply, ignore any declarations for properties we don't want,
while computing a pseudo-element's style.

I've imported a WPT test for this, which fails without this patch.

a6935299eb LibWeb: Correctly calculate static position rect when absolutely
positioned element is a descendant of inline-block

Sets inline block offsets in InlineFormattingContext.cpp, but this is
not enough. When static position rect is calculated during layout,
not all ancestors of abspos box may have their offsets calculated yet
(more info here: https://github.com/LadybirdBrowser/ladybird/pull/2583#issuecomment-2507140272).
So now static position rect is calculated relative to static containing
block during layout and calculation relative to actual containing block
is done later in
FormattingContext::layout_absolutely_positioned_element.

Fixes wpt/css/CSS2/abspos/static-inside-inline-block.html

d76f841994 LibWeb: Do not deform bitmaps partially outside the img-box
Instead of trying to manually determine which parts of a bitmap fall
within the box of the `<img>` element, just draw the whole bitmap and
let Skia clip the draw-area to the correct rectangle.

This fixes a bug where the entire bitmap was squashed into the rectangle
of the image box instead of being clipped.

With this change, image rendering is now correct enough to import some
of the WPT tests for object-fit and object-position. To get some good
coverage I have imported all tests for the `<img>` tag. I also wanted to
import a subset of the tests for the `<object>` tag, since those are
passing as well now. Unfortunately, they are flaky for unknown reasons.

This is the second attempt at this bugfix. The prior one was e055927ead
and broke image rendering whenever the page was scrolled. It has
subsequently been reverted in 16b14273d1. Hopefully this time it is not
horribly broken.

5331571fdc LibWeb: Handle interleaved table-row and table-row-group boxes
Before this change, we were always processing all row groups first,
and then all rows. This led to incorrect table layouts when rows and row
groups were encountered in anything but that order.

1b46a52cfc LibWeb: Always align inline text content to the alphabetic baseline
This fixes an issue where `vertical-align: middle` would incorrectly
shift the text away from the natural alphabetic baseline.

Fixing this makes many WPT table tests work correctly, so I'm also
importing one of them here. :^)

0fd0596dbf LibWeb: Support strings as list-style-types
We've long claimed to support this, but then silently ignored string
values, until 4cb2063577 which would
not-so-silently crash instead. (Oops)

So, actually pass the string value along and use it in the list marker.

As part of this, rename our `list-style-type` enum to
`counter-style-name-keyword`. This is an awkward name, attempting to be
spec-based. (The spec says `<counter-style>`, which is either a
`<counter-style-name>` or a function, and the `<counter-style-name>` is
a `<custom-ident>` that also has a few predefined values. So this is the
best I could come up with.)

Unfortunately only one WPT test for this passes - the others fail
because we produce a different layout when text is in `::before` than
when it's in `::marker`, and similar issues.

with double positions against a single color.

Further, also allows for `linear-gradient(black)` and similar
other gradient functions

de71eb9b13 LibWeb: Accept TableWrapper as containing block for abspos items
When an element is displayed as table, an anonymous table wrapper box
needs to be created for it. Among others, the position property of the
table element is then applied to the anonymous table wrapper box
instead. If the table happens to be positioned absolutely, the table
wrapper box may become the containing block for absolutely positioned
elements inside the table.

In the original code however, anonymous layout nodes were excluded from
becoming the containing block for an absolutely positioned element.
Because of this, the containing block was calculated to be the first
suitable parent block of the table wrapper box.

This incorrect containing block would result in a crash later on when
trying to size the absolutely positioned element inside the table. To
prevent this crash, the anonymous table wrapper box is now allowed to
become the containing block for absolutely positioned elements inside
a table.

The definition of containing block for an absolutely positioned element
in the spec does not mention anything about skipping anonymous boxes.
Additionally the rules for absolute positioning of tables
(https://www.w3.org/TR/css-tables-3/#abspos-boxes-in-table-root) imply
that a table wrapper box is indeed able to be the containing block for
absolutely positioned elements.

Also we now render the reference of color-mix-currentcolor-nested-for-
color-property.html properly. Which means that it's now different from
the actual test, that is still rendered incorrectly. In other word, the
false positive for this test is now turned into a true negative.
