Reviewed by Jean-Yves Avenard.
The HTML standard requires HTMLTrackElements with an empty trackURL to
generate an "error" event and move to the "ERROR" readyState/readiness
state. However, WebCore is returning early from the resource selection
algorithm when a HTMLTrackElement does not have a src attribute, which
causes the readyState to get stuck at Loading. Additionally, the media
element containing the track cannot progress its own readyState beyond
HAVE_CURRENT_DATA, which blocks play() commands from completing.
Remove the early return from HTMLTrackElement::scheduleLoad().
