Depending on the type of the calc() expression, the percentage_basis has
to be the same dimension type. Several places were already passing `
{}` for this, so let's make that an empty Variant instead of an
undefined Length. :^)
According to Fetch, we must send an Accept header with the value
"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
for document, iframe and frame requests.

This makes React react to checkboxes. Apparently they ignore the
"change" event in favor of "click" on checkboxes. This is a
compatibility hack for IE8.
Once we paint, it's way too late for this check to happen anyway.
Additionally, the spec's steps for retrieving the content document
assume that both the browsing context's active document and the
container's node document are non-null, which evidently isn't always the
case here, as seen by crashes on the SerenityOS 2nd and 3rd birthday
pages (I'm not sure about the details though).
Fixes#12565.
This is not a complete implementation of API, since we're also supposed
to accept an options dictionary as the third argument. However, a lot of
web content uses the boolean variant, and it's trivial to support.
I can't imagine how this happened, but it seems we've managed to
conflate the "event listener" and "EventListener" concepts from the DOM
specification in some parts of the code.
We previously had two things:
- DOM::EventListener
- DOM::EventTarget::EventListenerRegistration
DOM::EventListener was roughly the "EventListener" IDL type,
and DOM::EventTarget::EventListenerRegistration was roughly the "event
listener" concept. However, they were used interchangeably (and
incorrectly!) in many places.
After this patch, we now have:
- DOM::IDLEventListener
- DOM::DOMEventListener
DOM::IDLEventListener is the "EventListener" IDL type,
and DOM::DOMEventListener is the "event listener" concept.
This patch also updates the addEventListener() and removeEventListener()
functions to follow the spec more closely, along with the "inner invoke"
function in our EventDispatcher.
This basically copies some logic from FrameLoader to ImageLoader.
Ideally we'd share this code, but for now let's just get redirected
images to show up. :^)
When converting this code to use Optional, I accidentally left in the
initialization, so it *always* had a value, and always created a Length
from it. Oops.
This makes the selected-in-the-inspector outline appear in the right
place. We take the stroke-width into account when producing the
bounding box, which makes the fit nice and snug. :^)
We no longer include all the things, so each generated IDL file only
depends on the things it actually needs now.
A possible downside is that all IDL files have to explicitly import
their dependencies.
Note that non-IDL dependencies still remain and are injected into all
generated files, this can be resolved later if desired by allowing IDL
files to import headers.
Object.get() does not return empty values, this was causing the
constructed memory object to have a maximum of 0, which failed silently
in the constructor.
This enables, for example, clicking on the check box, dragging the mouse
over to the label, releasing the mouse to act as a click on the check
box.
This was implemented for labels / labelable nodes with the "for"
attribute already. This implements the same for labelable nodes that are
inside the label.
As noted, this is not entirely right, since we are using the computed
font's metrics instead of the initial font's metrics, but we do not
have a good way to obtain the latter.
We already supported "<input id=id><label for=id>".
This patch implements the other labeling mode, where the first labelable
descendant of the <label> element becomes the labeled control.
Pages such as https://html5test.com are testing all sorts of weird,
incomplete, and wrong HTML but can be useful or at least interesting for
development - let's try to avoid crashing the process.
This is needed to access the 'adjusted current node' in the 'Markup
declaration open state'. We don't want to create a full parser for
something like syntax highlighting, so it's optional (null) by default.
ACID3 test page throws exception about document.write. Let's at least
get rid of it by defining these stubs.
I added document.writeln too because it is similar.
If we try to <link> a stylesheet that was already cached, we'll get a
synchronous resource_did_load() callback. Because of this, it's
necessary to set up the document load event delayer *before* calling
set_resource(), as otherwise we'd be stuck without a load event forever.
