Setting the `width` or `height` properties of `HTMLCanvasElement` to a
value greater than 2147483647 will now cause the property to be set to
its default value.
Anchor the minimum functionality for this. WPT has an extensive suite
to test editing functionalities, but they all take a long time to
execute - so let's have a simple regression test in-tree for now.
Recently reported against the shadow realm proposal after running into
issues with WPT tests.
In a nested shadow realm, the associated realm is a shadow realm, not
the principal realm. One such issue this fixes is a crash when a nested
shadow realm performs an operation which requires the principal settings
object.
This change ensures that the correct default value of 0 is used and
that values greater than 2147483647 will fall back to the default value.
It also splits the display size concept into a separate method, as
this isn't supposed to be used when getting the IDL property.
This change makes Ladybird give the value of the aria-label attribute
the correct precedence for accessible-name computation required by the
“Accessible Name and Description Computation” and HTML-AAM specs and by
the corresponding WPT tests.
Otherwise, without this change, Ladybird fails some of the WPT subtests
of the test at https://wpt.fyi/results/accname/name/comp_label.html.
This change implements full support for the “A. Hidden Not Referenced”
step at https://w3c.github.io/accname/#step2A in the “Accessible Name
and Description Computation” spec — including handling all hidden nodes
that must be ignored, as well as handling hidden nodes that, for the
purposes of accessible-name computation, must not be ignored (due to
having aria-labelledby/aria-describedby references from other nodes).
Otherwise, without this change, not all cases of hidden nodes get
ignored as expected, while cases of nodes that are hidden but that have
aria-labelledby/aria-describedby references from other nodes get
unexpectedly ignored.
Attempting to set `HTMLInputElement.size` to 0 via IDL now throws an
IndexSizeError DOMException. Attempting to set it to a value larger
than 2147483647 results in it being set to the default value.
While the code that did this referred to the HTML spec, other browsers
appear not to have this behavior when parsing XML, and it breaks a WPT
subtest.
This change does not appear to break any tests, and fixes 1 WPT subtest.
If `HTMLMarqueeElemnt.scrollAmount` or `HTMLMarqueeElemnt.scrollDelay`
is set to a value larger than 2147483647, then it should be set to its
default value.
According to the HTML specification, the `size` attribute of an input
element must be a valid non-negative integer greater than zero. If the
value is invalid or set to `0`, the default size of `20` should be used.
This small change fixes one issue identified in
https://wpt.live/html/rendering/widgets/input-text-size.html
The WPT test suite was also automatically imported.
Use discrete animation when the number of components or the types
of corresponding components do not match. This commit does not cover
all cases, but adds FIXME comments in the appropriate places.
