Steps to reproduce the problem:
video.preload = 'metadata';
video.onloadedmetadata = function () {
   console.log('loaded metadata');
};
video.src = 'http://media.w3.org/2010/05/sintel/trailer.mp4';

What is the expected behavior?
it should log 'loaded metadata'

What went wrong?
event is never fired and handler is never called
