As defined in: https://w3c.github.io/pointerevents
With the exception of the getCoalescedEvents and getPredictedEvents
APIs.
There are still many other parts of that spec (such as the event
handlers) left to implement, but this does get us at least some of the
way.
If initial src of an iframe is "about:blank", it does synchronous
navigation that is not supposed to be interleaved by other navigation
or usage of Document.open().

A bunch of this is leftover from pre porting over to new AK::String.
For example, for functions which previously took a ByteString const&
now accepting a StringView.
Fixes a bug when session history traversal queue task could be
interrupted by another SHTQ task execution. For example:
1. SHTQ timer callback starts executing a task from the queue.
2. spin_until() is invoked during task execution.
3. SHTQ timer callback starts executing a task from the queue.
...because existance of this method conflicts with the purpose of
having a queue as it allows to start executing next task in the middle
of ongoing task.
For example:
1. SHTQ timer starts executing a task.
2. Task does SHTQ::process().
Another example:
1. SHTQ::process() start executing a task.
2. task does SHTQ::process().
`HTMLIFrameElement::inserted()` does following:
1. Init a new navigable. This step appends a task on session history
traversal queue (SHTQ) that creates a new nested history.
2. Process iframe's attributes
Processing of iframe's attributes might result in synchronous
navigation that fails to get active SHE if SHTQ task that creates
new nested history is not yet completed.
Before this change, a workaround involved forcing the processing of
SHTQ, which was terrible hack because it could occur in the middle of
another SHTQ task.
This change removes the need for "force SHTQ processing" by ensuring
that the processing of iframe's attributes is always executed after
the iframe's navigable nested history has been created.
Workaround spec bug by explicitly carrying information whether
navigation is sync (History api, fragment change) or not.

While this is the default for an underlying socket, it doesn't seem good
to have this as the default for our socket wrapper.
This fixes a crash in ladybird when connecting to the python HTTP server
with HTTPS.
If navigation early returns before reaching "finalize a cross document
navigation" then we have to make sure delaying load events is disabled.

...and use HeapFunction instead of SafeFunction for task steps.
Since there is only one EventLoop per process, it lives as a global
handle in the VM custom data.
This makes it much easier to reason about lifetimes of tasks, task
steps, and random stuff captured by them.
This allows you to click on a <img> that has an ismap attribute, and
will result in the navigation URL having the coordinates appended as a
query to the URL.
It's a little bit confusing and awkward that we have `url` _and_
`url_string` here, but let's just fix the typo so that we correctly pass
through the URL with the given suffix (if any).
Currently, nothing is actually passing through this suffix - so it
doesn't fix anything yet, but it becomes relevant in the next commit.
This is often used on login forms, for example, to toggle the visibility
of a password. The site will change the <input> element's type to "text"
to allow the password to show.
No need to force an allocation. This makes a future patch a bit simpler,
where we will have the encoding as a String. With this patch, we won't
have to convert it to a ByteString.
f66d33423b was not sufficient to ensure
document destruction when a child navigable is destroyed. This is
because a navigable was remove from the set of all navigables too early
which led to `Navigable::navigable_with_active_document()` being unable
to find a navigable that is still in the process of destruction.
This change solves that by making all steps of a navigable destruction
to happen in afterAllDestruction callback.
Unfortunately, writing a test to verify document destruction is
challenging because no events are emitted to indicate that it has
happened.
Switching away from SafeFunction immediately backfired here, as we're
dealing with two layers of captures, not one.
Let's do the correct fix, which is to use HeapFunction. This makes the
API and its behavior explicit, and keeps captures alive as long as the
HeapFunction is alive.
Fixes#23819.

Before this change it only worked because of another bug in
`EventLoop::spin_processing_tasks_with_source_until()`
where we execute tasks regardless of whether they are runnable or not.
This collection has some pretty strange behaviour, particularly with the
IsHTMLDDA slot which is defined in the javascript spec specifically for
this object.
This commit implements pretty much all of this interface, besides from
the custom [[Call]].
There is also no caching over this collection. Since it is a live
collection over the entire document, the performance is never going to
be great, and I am not convinced any speedup for this legacy interface
is worth a massive cache.
These changes do not solve hanging `location.reload()` and
`location.go()` but only align implementation with the latest edits in
the specification.
`WindowProxy-Get-after-detaching-from-browsing-context` test output is
affected because `iframe.remove();` no longer synchronously does
destruction of a document, but queues a task on event loop.

This adds an IPC for chromes to mute a tab. When muted, we trigger an
internal volume change notification and indicate that the user agent has
overriden the media volume.
