Hm, this change may affecting some layout tests, too:

I already filed a bug about this and proposed a fix: https://bugs.webkit.org/show_bug.cgi?id=216258.
About layout tests, I can only reproduce failure of fast/animation/request-animation-frame-throttling-lowPowerMode.html so far: https://bugs.webkit.org/show_bug.cgi?id=216261.
