The existing implementation has some pre-existing issues where it is
incorrectly assumes that byte offsets are given through the IDL instead
of UTF-16 code units. While making these changes, leave some FIXMEs for
that.
HTMLTextAreaElement also needs to be told when its contained text node
has been edited, so let's make this functionality work for anyone who
extends the new EditableTextNodeOwner interface class.
Instead of having a nested enum within a struct, use the macro
AK_ENUM_BITWISE_OPERATORS to add all the convienent has_flag free
functions and such for ease of use.
We never implemented this for History::pushState/popState, and now that
we're working on the Navigable changes, we don't need this legacy entry
with its legacy name.
With this change, elements that want to receive viewport rect updates
will need to register on document instead of the browsing context.
This change solves the problem where a browsing context for a document
is guaranteed to exist only while the document is active so browsing
context might not exit by the time DOM node that want to register is
constructed.
This is a part of preparation work before switching to navigables where
this issue becomes more visible.
Using `Core::Timer` that doesn't implicitly convert callback to
`JS::SafeFunction` fixes the bug when `BrowsingContext` is never
destroyed because of cyclic dependency between callback and
`BrowsingContext`.
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
In order to follow spec text to achieve this, we need to change the
underlying representation of a host in AK::URL to deserialized format.
Before this, we were parsing the host and then immediately serializing
it again.
Making that change resulted in a whole bunch of fallout.
After this change, callers can access the serialized data through
this concept-host-serializer. The functional end result of this
change is that IPv6 hosts are now correctly serialized to be
surrounded with '[' and ']'.
BrowsingContext::set_active_document() may end up asking for the Page's
top level browsing context before Page has one. Do a workaround for now
where we have an API to ask if it's initialized.
Long-term we should find a cleaner solution.
This fixes an issue where loading an iframe would cause the current
browser tab title to get overwritten with an empty string.
The problem is that nested browsing contexts can be considered "top
level" during their initialization, but only one browsing context is
ever the Page::top_level_browsing_context(), so that's what we check.
