    <thetext>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.</thetext>

    <thetext>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&apos;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&apos;t run.

See AnimationControllerPrivate::pauseAnimationAtTime...

    if (compAnim-&gt;pauseAnimationAtTime(name, t)) {
        renderer-&gt;node()-&gt;setNeedsStyleRecalc(SyntheticStyleChange);
        startUpdateStyleIfNeededDispatcher();
        return true;
    }</thetext>
