This fixes a timeout in the included test. In order for the
test to run properly in our test harness it is modified slightly
(as we are loading the HTML from a file:// URL).
:heading() now matches based on a computed heading level, which is based
on the level of the tag (h1, h2, etc) and then modified by these two new
attributes.
I'm caching this heading level on HTMLHeadingElement, based on the dom
tree version. That's more invalidation than is actually needed, but it
saves us calculating it over and over when the document hasn't changed.
The failing test cases are:
- Implicit headingreset for modal dialogs which is apparently unspecced
and controversial.
- Not walking the flat tree properly. A flat tree ancestor of a
slot-assigned element is its slot, which is something we don't do
anywhere that I could find. I've made a note to look into this later.
We also don't implement the `ReflectRange` IDL attribute yet, which
means we're not clamping the read value of `headingOffset`.

Introduce the HTMLSelectedContentElement and integrate it into
<select>, <option> and HTMLParser.
See whatwg/html#10548.
There are two bugs with WPT tests which causes the third subtest
in selectedcontent.html and selectedcontent-mutations.html fail.
See whatwg/html#11882, web-platform-tests/wpt#55849.
- Rename HTMLOptionElement's `owner_select_element()` to
`nearest_select_element()` to better match spec terminology.
- Update HTMLSelectElement's option list related algorithms.
This change is part of the customizable <select> spec work.
See whatwg/html#10548.
Previously, validation_message() always returned a hardcoded "Invalid
form" string, now it correctly returns the custom validity error
message when the element is suffering from a custom error.
Other validation errors still return the "Invalid form" message.
This introduces a new `is_integral_multiple` method that replaces the
`fmod(...) != 0` check. This fixes some WPT-Tests, where the step
cannot be accurately represented as a double.
This implements parsing part of customizable <select> spec update.
See whatwg/html PR #10548.
Two failing subtests in `html5lib_innerHTML_tests_innerHTML_1.html`
and `customizable-select/select-parsing.html` are due to the spec
still disallowing `<input>` inside `<select>`, even though Chrome
has already implemented this behavoir (see whatwg/html#11288).

As we now have a field in that dictionary, I removed the separate
`source` parameter from ToggleEvent::create(). Also updated the
relevant test.
Currently, ImageProvider::current_image_bitmap takes a Gfx::IntSize
argument which determines the size of the returned bitmap. The default
value of this argument is 0x0 which causes the function to return
nullptr. This behavior is evidently unintuitive enough that it has lead
to incorrect usage in multiple places. For example, the 2D canvas
drawImage method will never actually draw anything because it calls
current_image_bitmap with no arguments. And the naturalWidth and
naturalHeight of an image will always return 0 (even after the image has
loaded) for the same reason.
To correct this and hopefully avoid similar issues in the future,
ImageProvider::current_image_bitmap will be renamed to
current_image_bitmap_sized, and the default value for the size argument
will be removed. For consistency, a similar change will be made to
SVGImageElement::default_image_bitmap.
The existing current_image_bitmap function will no longer take a size
argument. Instead it will always return a bitmap of the image's
intrinsic size. This seems to be what most existing callers had already
assumed was the function's behavior.
This fixes a bug in the algorithm for determining if radio buttons are
missing their value. Previously it was only checked if the button
itself is required. Now the algorithm checks if the radio button group
contains a required radio button in order to determine if the value is
required.
The spec for checking the no-validate state ends with a default return
value of "false". However, we were only hitting this case for form-
associated elements. If the submitter is the form itself, we want to
enter the form validation steps.
This adapts the implementation of `is_mutable` to align more closely
with the spec. Specifically, it is now also taken into account whether
the element is enabled.
This porting effort makes it pretty clear we will want a UTF-16-aware
GenericLexer. But for now, we can actually make ASCII assumptions about
what we are parsing, and act accordingly.
Documents created by DOMParser and fragment documents do not
have an origin set on the document by the spec. These documents
also happen to never become fully active.
By properly implementing the steps for the <img> element to only
update the image data for documents which are fully active, this
fixes a crash for img elements in these types of documents.
Unfortunately, this is not a full fix for the microtask queue case.
This is because it seems possible for node document for an <img>
element to be changed during the microtask queue for that document.
It is not clear to me how this can be fixed in a nice way.
This commit implements the fallback to the documents fallback base url
if the href of the first base element is a data or javascript url.
Additionally the frozen base url is set, if a base element becomes the
first base element with an href content attribute because the previous
one got removed.
Fixes at least three WPT test that were previously timing out:
- html/semantics/embedded-content/media-elements/error-codes/error.html
- html/semantics/embedded-content/media-elements/location-of-the-media-resource/currentSrc.html
- html/semantics/embedded-content/the-video-element/video_crash_empty_src.html
This implements the previously stubbed out `report_validity` method.
The specification is not very clear on how to exactly report the
validity. For now, we bring the first visible invalid control into
view and focus it. In the future, however, it would make sense to
support more complex scenarios and be more aligned with the other
implementations.
