fast/animation/request-animation-frame-throttling-lowPowerMode.html

It was passing before r282383, after which it started failing. And after r282490, it's always timing out. The frame rate setting is correctly halved to 30 (calculated by AnimationFrameRate.cpp), but somehow the second requestAnimationFrame callback is called only after the test times out.

Diff of the failure before r282490:
