Should <video hidden> be muted?

<Hixie> zcorpan_: technically <video hidden> means "this isn't relevant"  
and so we should probably make it mute the audio as well

The spec does not currently say this at the moment.

I haven't thought about this enough to have an opinion on whether it would  
be a good thing or not to mute the audio.
