This will be used to look up a document's node navigable. It might be
nice to have a direct pointer from Document to its Navigable, but at
the moment I don't understand the algorithms well enough to maintain
that linkage.
This will fetch the URL indicated by the poster attribute when it's set,
changed, or removed. The spec doesn't say how to handle animated poster
images, so we just grab the first frame of the image, which seems to
match other implementations.
This will be needed by the layout node, which may change what is painted
when the position of the frame image is not the same as the element's
current time.

We are currently using the fetch controller's terminate() method to stop
ongoing fetches when the HTMLMediaElement load algorithm is invoked.
This method ultimately causes the fetch response to be a network error,
which we propagate through the HTMLMediaElement's error event. This can
cause websites, such as Steam, to avoid attempting to play any video.
The spec does not actually specify what it means to "stop" or "cancel" a
fetching process. But we should not use terminate() as that is a defined
spec method, and the spec does tend to indicate when that method should
be used (e.g. as it does in XMLHttpRequest).
This is the first step towards implementing the new "navigable" concept
from the HTML spec.

The "browsing context container" concept in the HTML spec has been
replaced with "navigable container". Renaming this is the first step of
many towards implementing the new world.

When clicking on the media timeline, compute the percentage along the
timeline's width the user clicked, and set the playback time to the same
percentage of the video's duration.
When the control bar is shown, do not toggle playback when clicking on
the control bar, unless the click target is the playback button. This
will let us implement clicking on the timeline to seek.
Note that this requires caching some layout rects on the video element.
We need to remember where the corresponding layout boxes are, and we
can't cache them on the layout box, as that may be destroyed any time.
The on_end_of_stream callback was added to notify clients that video
playback has stopped when we didn't have a way to retrieve the playback
state from Video::PlaybackManager. Now that we do, we should consolidate
on using the on_playback_state_change callback to detect such changes.
Adds step and document_state properties. Both will be required for
further navigables spec implementation.

This represents the new "document state" concept from the HTML spec.
Document states are primarily used in session history entries.

These will need to float around more than they're currently able to.
Put them on the GC heap to prepare for that.

This now defaults to serializing the path with percent decoded segments
(which is what all callers expect), but has an option not to. This fixes
`file://` URLs with spaces in their paths.
The name has been changed to serialize_path() path to make it more clear
that this method will generate a new string each call (except for the
cannot_be_a_base_url() case). A few callers have then been updated to
avoid repeatedly calling this function.
