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.
Importing these tests now because they are for input-element types that
have requirements related to the constraint-validation API — which we’ve
been implementing recently.
This commit only imports tests, without any changes to our code.
Type changes are now signaled to radio buttons. This causes other radio
buttons in the group to be unchecked if the input element is a checked
radio button after the type change.
This change adds “default step” and “step scale factor” handling for all
remaining HTMLInputElement input types for which the spec defines such
and that we didn’t yet have handling for.
Previously, we would only invalidate style when setting the `media` IDL
attribute; changing the attribute via `setAttribute()` and
`removeAttribute()` had no immediate effect.
This change implements the requirements for the “suffering from an
overflow” and “suffering from an underflow” algorithms for
HTMLInputElement constraint validation.
This change fixes a bug in our implementation of the “step base”
algorithm at https://html.spec.whatwg.org/#concept-input-min-zero. We
were using the “value” IDL/DOM attribute in a particular step, where the
spec instead actually requires using the “value” content attribute.
This change implements HTMLInputElement type=email constraint validation
in conformance with the current spec requirements (which happens to also
produce behavior that’s interoperable with other existing engines).
This change implements HTMLInputElement type=url constraint validation
in such a way as to match the behavior in other existing engines (which
is, however, very different from what the spec currently requires).
