Comment (by gk):

 Upon further thought I wonder whether the approach in my patch is actually
 a good one. I mean we don't set `media.webm.enable` to `false` either to
 get WebM videos to adhere to click-to-play governed by NoScript. I fear we
 are essentially breaking MSEs on higher security level this way instead of
 making it click-to-play.
