smfr provided a manual test case in
bug 114067
, which we should automate and check in. He used the test case to find a regression caused by the patch in
bug 109098
.

An API to dump the current accelerated animations on a platform layer could be a good way to test this. I looked at using the Internals::pauseTransitionAtTimeOnElement API to take a snapshot in the middle of an accelerated animation, but it looks like it fast-forwards the animation to the desired time and then does a style recalculation. I don't think this would catch the kind of regression that occurred in
bug 114067
, where the start state and end state were fine but the accelerated animation didn't run. See AnimationControllerPrivate::pauseAnimationAtTime... if (compAnim->pauseAnimationAtTime(name, t)) { renderer->node()->setNeedsStyleRecalc(SyntheticStyleChange); startUpdateStyleIfNeededDispatcher(); return true; }
