Recording of a timeline in web inspector

One final observation - when pausing the video, we jump back up to 60 FPS.

So one more random theory - perhaps it's not throttled, but it's not correctly hooked back up to a v-sync timer for rAF in those cases. As a fallback, it just schedules the next rAF for 16.66ms later. That looks legit from the timeline recording in Web Inspector...
