Comment (by arthuredelstein):

 I built the latest tor-browser.git, applied this patch to torbutton.

 * First I visited https://arthuredelstein.github.io/tordemos/resource-
 locale.html. I could see in the web console that it correctly blocked
 reading the resource:// files.
 * Then I visited https://mdn.github.io/learning-area/html/multimedia-and-
 embedding/video-and-audio-content/simple-video.html and found that the
 video controls are not available and clicking on the video does not cause
 it to play. Reverting the patch from comment:2 restores the video

 So it appears something additional needs to be done to activate the
 whitelist? As we're on a tight deadline I will continue to investigate.
