As it currently stands, load() also resets the pause state and reloads the
media resource, making it a bit useless for this need. This is why I
considered a reset() function, which would essentially allow you to reset
the current resource to the initial playback state, i.e. including being in
pause state (if the element has a pause attribute) and resetting the
currentTime to 0 and showing the poster. We should probably not reset the
playbackRate and the volume though, or any of the selected TimedTracks, and
of course we should avoid re-downloading the resource.
