This stopped being called for anything without a navigable container
after 76a97d8, due to the early return. This broke SVG <use> elements
that reference elements defined later in the document.
This aligns Workers and Window and MessagePorts to all use the same
mechanism for transferring serialized messages across realms.
It also allows transferring more message ports into a worker.
Re-enable the Worker-echo test, as none of the MessagePort tests have
themselves been flaky, and those are now using the same underlying
implementation.
This avoids doing pointless plotting for scanlines that will never be
seen.
Note: This currently can only clip edges vertically. Horizontal clipping
is more tricky, since edges that are not visible can still change how
things accumulate across the scanline.
Fixes#22382
Sadly, this causes a bunch of LibWeb test churn as this change
imperceptibly changes the final rasterized output.
We would previously not return a RadioNodeList in the curious case where
a named item resolves to two different elements within the form.
This was not a problem when calling namedItem directly in the IDL as
named_item_or_radio_node_list shadows named_item but is exposed when
calling the property through array bracket notation (as an example).
Fix this, and add a bunch more tests to cover
HTMLFormControlsCollection.
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.

We were previously assuming that the input offsets and lengths were all
in raw byte offsets into a UTF-8 string. While internally our String
representation may be in UTF-8 from the external world it is seen as
UTF-16, with code unit offsets passed through, and used as the returned
length.
Beforehand, the included test included in this commit would crash
ladybird (and otherwise return wrong values).
The implementation here is very inefficient, I am sure there is a
much smarter way to write it so that we would not need a conversion
from UTF-8 to a UTF-16 string (and then back again).
Fixes: #20971
Calling test() multiple times in the same test file is not actually
valid, and can cause the following test to hang forever. So let's stop
doing that in the one test that did so, and also prevent the same
mistake happening again. :^)
Throwing an exception on subsequent test() calls means that we don't
hang, the test will fail with missing output, and we get a log message
explaining why.
This is a pretty straightforward test, but I managed to make this crash
on real sites while trying to fix#20971 without any other test in the
existing suite failing.
This is to allow future changes to do cross-process MessagePorts in an
implementation-agnostic way. Add some tests for this behavior.
Delivering messages that were posted to a MessagePort just before it was
transferred is not yet implemented still.
Fixes following mistakes:
- "scrolling box" for a document is not `scrollable_overflow_rect()`
but size of viewport (initial containing block, like spec says).
- comparing edges of "scrolling box" with edges of target element
does not make any sense because "scrolling box" edges are relative
to page while result of `get_bounding_client_rect()` is relative
to viewport.
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.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

With this change, Document now always has a Web::Page. This means we no
longer rely on the breakable link between Document and BrowsingContext
to find a relevant Web::Page.
Fixes#22290
This fixes the issue that occurred when, after clicking an inline
paintable page would always scroll to the top. The problem was that
`scroll_an_element_into_view()` relies on `get_bounding_client_rect()`
to produce the correct scroll position and for inline paintables we
were always returning zero rect before this change.
As outlined in: https://www.w3.org/TR/selectors-4/#compat
We now do not treat unknown webkit pseudo-elements as invalid at parse
time, and also support serializing these elements.
Fixes: #21959
This is currently only used by CSS attr ref tests, but is useful outside
of attr ref tests as well. Give a more generic name to this ref file for
this usage.
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.
(Or rather, bring offsetLeft and offsetTop closer to spec, and implement
the previously-missing offsetParent)
This makes mouse inputs on https://nerget.com/fluidSim/ work properly.
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.
