Before this change, we used the wrong insertion point for flex items
in reverse layouts with `justify-content: normal`. This caused flex
items to overflow the flex containers "backwards" from the start edge.
- We now propagate changes in font and line-height to anonymous wrappers
when doing a partial style update after invalidation.
- We no longer (incorrectly) propagate style from table wrapper boxes
to the table root, since inheritance works in the other direction.
Fixes#22395
This change fixes the function that calculates the number of auto-fill
tracks, ensuring it uses height when applied to rows, instead of
assuming that it always operates on columns.
Fixes the mistake that gaps are counted as if they exist after each
track, when actually gaps are present only between tracks.

CSSPixels should not be wrapped into CSS::Length before being passed
to resolved() to end up resolving percentages without losing
precision.
Fixes thrashing layout when 33.3333% width is used together with
"box-sizing: border-box".
Percentage vertical margin and padding values are relative to the
containing block *width*, not *height*. This has to be one of the most
commonly recurring mistakes we make :^)
Before this change, parsed grid-template-columns/grid-template-rows
were represented as two lists: line names and track sizes. The problem
with this approach is that it erases the relationship between tracks
and their names, which results in unnecessarily complicated code that
restores this data (incorrectly if repeat() is involved) during layout.
This change solves that by representing line definitions as a list of
sizes and names in the order they were defined.

The fix here was to stop using StringBuilder::append(char) when told to
append a code point, and switch to StringBuilder::append_code_point(u32)
There's probably a bunch more issues like this, and we should stop using
append(char) in general since it allows building of garbage strings.
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.
