Elements are now collected according to paint order as spec says,
replacing the depth-first traversal of the paint tree with hit-testing
on each box.
This change resolves a FIXME in an existing test and adds a new
previously non-working test.
Change 'dom_node_for_event_dispatch' to locate the closest layout node
with a DOM node instead of only checking the direct ancestor.
This fixes hit-testing for buttons because they are wrapped into
multiple anonymous layout nodes (internally we use flex formatting for
them).
This API seems to be used by WPT for sending synthetic input events.
Implementing the naive translation of elementFromPoint to the spec steps
for this algorithm turns 4 'tests had errors unexpectedly' and 3 'tests
had timeouts unexpectedly' into 1 pass and 7 'tests had unexpected
subtest results' on the infrastructure/ subdirectory of WPT.
Implements following rule from CSS Overflow Module Level 3:
"The visible/clip values of overflow compute to auto/hidden
(respectively) if one of overflow-x or overflow-y is neither visible
nor clip."
When an element with an ID is added to or removed from the DOM, or if
an ID is added, removed, or changed, then we must reset the form owner
of all form-associated elements who have a form attribute.
We do this in 2 steps, using the DOM document as the messenger to handle
these changes:
1. All form-associated elements with a form attribute are stored on the
document. If the form attribute is removed, the element is removed
from that list as well.
2. When a DOM element with an ID undergoes any of the aforementioned
changes, it notifies the document of the change. The document then
forwards that change to the stored form-associated elements.
This change makes hit-testing more consistent in the handling of hidden
overflow by reusing the same clip-rectangles.
Also, it fixes bugs where the box is visible for hit-testing even
though it is clipped by the hidden overflow of the containing block.
The hit-testing position is now shifted by the scroll offsets before
performing any checks for containment. This is implemented by assigning
each PaintableBox/InlinePaintable an offset corresponding to the scroll
frame in which it is contained. The non-scroll-adjusted position is
still passed down when recursing to children because the assigned
offset accumulated for nested scroll frames.
With this change, hit testing works in the Inspector.

Just creating a stream on the JS heap isn't enough, as we will later
crash when trying to read from that stream as it hasn't been properly
initialized. Instead, until we have teeing implemented (which is a
rather huge part of the Streams spec), create streams using proper AOs
that do initialize the stream.
For some reason on macOS with ASAN enabled, the test promises in
HTML/Window-postMessage do not resolve. These promises wait for both
the in-document and the blob url iframes to load. It's not clear why
this works fine in Linux nor why the onload handler doesn't fire
when the iframe has already loaded.
This attribute has some compatbility issues...
- The spec says it should be an SVGAnimatedRect which contains
a DOMRect and a DOMReadOnlyRect.
- Blink gives you an SVGAnimatedRect with 2x SVGRect
- Gecko gives you an SVGAnimatedRect with 2x SVGRect? (nullable)
I ended up with something similar to Gecko, an SVGAnimatedRect
with 2x DOMRect? (nullable)
With this fixed, we can now load https://polar.sh/ :^)
Window and other global objects are not technically legacy platform
objects, and have other ways to override their setters and getters.
However, Window does need to share some code with the legacy platform
object paths, and simply adding another bool check to the mix seems
the shortest putt.
HTML fragments are parsed with a temporary HTML document that never has
its flag set to say that it is ready to have scripts executed. For these
fragments, in the HTMLParser, these scripts are prepared, but
execute_script is never called on them.
This results in the HTMLParser waiting forever on the document to be
ready to have scripts executed.
To fix this, only wait for the document to be ready if we are definitely
going to execute a script.
This fixes a hang processing the HTML in the attached test, as seen on:

When the caller of NumericCalculationNode::resolve() does not provide
a percentage_basis, it expects the method to return a raw percentage
value.

With this change, a stacking context can be established by any
paintable, including inline paintables. The stacking context traversal
is updated to remove the assumption that the stacking context root is
paintable box.
