Don't we need to keep this?
if (UserGestureIndicator::processingUserGesture())
  removeBehaviorsRestrictionsAfterFirstUserGesture();

Done. Ignoring legacy compat it doesn't really make sense, but
http://foolip.org/2014/02/10/media-playback-restrictions-in-blink/demo.html
depends on it to circumvent the restrictions on play()...

-        removeBehaviorsRestrictionsAfterFirstUserGesture();
     prepareForLoad();
     loadInternal();
     prepareToPlay();
