When the HTML5 preload attribute is set to 'none' or when using Safari (even when the
preload attribute is not 'none'), the video does not resume playing after the quality is
changed using the quality selector menu. The quality selector plugin was listening for the
'loadeddata' event in order to know when to resume playback, but the 'loadeddata' event
does not fire when the preload attribute is set to 'none', and Safari does not fetch
enough data to emit a 'loadeddata' event.
