Screen recording of apparent rAF throttling

Screen recording showing some navigations seem to get throttled rAF callback rates. When not screen recording the throttled rates seem a little lower - 40-45 FPS, but even here it's apparent we're not getting the solid 60 FPS I'd expect for this content until Safari is restarted.
