Opps, forgot to answer this one. I strongly feel that both <audio> and 
<video> should make sound for display:none elements. The CSS display 
property should only affect the visual appearance of the node.

Additionally, it's more efficient for us, and simpler for the author, if 
hidden-but-played audio/video elements don't create a frame and don't 
affect layout.
