STR 1 (simplest steps, mild blinking):
 1. Prerequisite: make sure to have added a media-related pref to about:config, like `media.getusermedia.audiocapture.enabled`.
 3. Open about:webrtc and wait 10 seconds

Expected result:
- No blinking (though if I look closely, the `User Set WebRTC Preferences` section blinks once every ~10 seconds or so).

Actual result:
- The `User Set WebRTC Preferences` blinks every 0.5 seconds.

STR2: 
 1. First open https://jsfiddle.net/jib1/yxbLvjm6/ and allow camera+mic
 2. Run STR 1

In this case, when I click `Show details`, I see entire tables of data (like `Ice Stats` and `Estimated Bandwidth`) flicker every 0.5 seconds.

I'm marking this as a regression since the symptoms went from acceptable to unacceptable.

There's likely a preexisting issue here with how about:webrtc updates itself on a timer, so feel free to lob this over to WebRTC, after you're satisfied that bug 1613705 isn't introducing anything that might affect other web pages similarly.

Any theories on why the symptoms got a lot worse, and advice on how to live-update documents properly if anyone has them, would also be welcome.
