With this change "display: contents" ancestors are not considered as
insertion point for inline nodes similar to how we already ignore them
for non-inline nodes.

The styling of elements using the `use_pseudo_element()` was only
applied on layout. When an element style was recomputed later that
styling was not overruled with the pseudo element selector styles.
This moves the styling override from `TreeBuilder.cpp` to
`StyleComputer.cpp`. Now the styles are always correctly applied.
I also removed the method `property_id_by_index()` because it was
not needed anymore.
Als some calls to `invalidate_layout()` in the Meter, Progress and
Select elements where not needed anymore because the style values
are update on the changing of the style attribute.
This fixes issue #22278.
Out-of-flow boxes (floating and absolutely-positioned elements) were
previously collected and put in the anonymous block wrapper as well, but
this actually made hit testing not able to find them, since they were
breaking expectations about tree structure that hit testing relies on.
After this change, we simply let out-of-flow boxes stay in their
original parent, preserving the author's intended box tree structure.
Sizing already worked correctly, but before this change, we were too
aggressive with inserting line breaks when negative margins would
still an atomic inline to fit on the line.
After commit ff48b7333c, we remove shadow
roots from elements that are removed from the DOM. Setting a node's
shadow root to null also sets that shadow root's host to null. Thus, the
comment in Node::is_shadow_including_descendant_of that assumes the host
is always non-null is not true.
The test added here would previously crash when interacting with a node
that is a descendant of a removed shadow root.
Setting the marker's content width here is causing the text that follows
the marker to be indented a bit too much. This is noticeable when a line
with a disclosure marker is followed by a line with any other marker. It
previously would look something like:
> Text inline with disclosure-closed marker
* Text inline with circle marker
# Text inline with square marker
Now the disclosure marker line matches other marker types:
> Text inline with disclosure-closed marker
* Text inline with circle marker
# Text inline with square marker
When a box does not have a top, left, bottom, or right, there is no
need to adjust the offset for positioning relative to the padding edge,
because the box remains in the normal flow.
By using available_inner_space_or_constraints_from(available_space), we
ensure that the available space used to calculate the min/max content
height is constrained by the width specified for the box itself
(I know that at least GFC always expects available width to be
constrained by specified width if there is any).

The elements this hack was being used for were grouping elements, and
can be properly sized: https://svgwg.org/svg2-draft/struct.html#Groups.
Note: Other than one test change the elements here are already covered
by layout tests.
This makes use of the new Gfx::Path::text() to handle SVG text elements,
with this text is just a regular path, and can be manipulated like any
other graphics element.
This removes the SVGTextPaintable and makes both <text> and geometry
elements use a new (shared) SVGPathPaintable. This is identical to the
old SVGGeometryPaintable. This simplifies painting as once something is
resolved to a Gfx::Path, the painting logic is the same.
When calculating the width of text using a bitmap font, a glyph spacing
is added at the end of each fragment, including the last one. This meant
that everything was 1 pixel too long. This bug did not affect vector
fonts.
Before this change, we were doing it after every layout, which meant
that already-propagated overflow could be propagated again, which led to
incorrect scrolling behavior.
Previously, all SVG <text> elements were zero-sized boxes, that were
only actually positioned and sized during painting. This led to a number
of problems, the most visible of which being that text could not be
scaled based on the viewBox.
Which this patch, <text> elements get a correctly sized layout box,
that can be hit-tested and respects the SVG viewBox.
To share code with SVGGeometryElement's the PathData (from the prior
commit) has been split into a computed path and computed transforms.
The computed path is specific to geometry elements, but the computed
transforms are shared between all SVG graphics elements.
Changing `try_compute_width()` to return width and margins, instead of
mutating them in the box's state makes it works in cases when box has
min-width or max-width and this function needs to be called multiple
times.

As spec comment in the code says we should use item’s max-content
contribution to calculate flex fraction.
Likely, it was calculate_max_content_size() because we didn't have
calculate_max_content_contribution() when this function was implemented
initially.
Rewrites the grid area building to accurately identify areas that span
multiple rows. Also now we can recognize invalid areas but do not
handle them yet.
Grid items should respect alignment properties if top/right/bottom/left
are not specified.
This change adds a separate implementation of
layout_absolutely_positioned_element that is extended with support for
alignment.
If the first pass of rows sizing results in the container's automatic
height being less than the specified min-height, we need to run a
second pass using the updated available space.
