I changed window.Audio, and did nothing for HTMLMediaElement or any other
constructors, as I was not aware that this was the desired behavior.

Just returning undefined for the constructor is incorrect - you should instead
follow the example for window.Audio, which actually removes the associated
attribute from the window object.

Case in point: with the patch attached to this bug, "typeof HTMLMediaElement
=== 'undefined'", but "'HTMLMediaElement' in window" would still return true.
If you follow the approach I used for window.Audio, then you'd get the correct
behavior in both cases.
