Re: [remote-playback] Should rendering behavior of the remote-d media element be specified?

@mfoltzgoogle I think we're not discussing freezing the element's layout, but the ```videoWidth``` and ```videoHeight``` properties. That way if the page doesn't do anything to resize the remotely played element, it won't break because the UA suddenly changed the size of the video to say full HD.
The page can still detect if remote playback is happening and resize the element any way it wants.

The rendering should be up to the UA:
- show some default remote playback UI
- show the last rendered frame / poster image
- keep rendering the media as is
Some things like closed captions may continue being rendered within the media element, for instance, if the remote playback device doesn't support it.

We should advise the UAs to suspend the local playback except for the parts that are needed for remote playback implementation to work (e.g. mirroring/remoting) to preserve resources, esp. if the page will show its own UI on top or instead of the element during remote playback.
