I find this tempting, despite the costs here.  The permissions prompt
is a popup of a sort, so applying the same protection makes a great
deal of sense.  It's obviously a non-issue on sites where permissions
are persisted, so I'm inclined quite favourably toward this.

The other suggestions, less so.  Enhancing CSP might be a good idea to
cover this, rather than the sandboxing stuff.  I have CSP folks within
spitting distance, so I'll ask.  The question of WebRTC as a whole is
probably more interesting in this regard.
