No, I do not have a reproducer. I just happen to remember it crashed yesterday displaying about:overview (which does not even contain any animations).

FWIW there is a FIXME in TreeResolver::createAnimatedElementUpdate one line beneath the crash:

        update.change = determineChange(rendererToUpdate->style(), *animatedStyle);
        // If animation forces render tree reconstruction pass the original style. The animation will be applied on renderer construction.
        // FIXME: We should always use the animated style here.
        update.style = update.change == Detach ? WTFMove(newStyle) : WTFMove(animatedStyle);

But that looks probably unrelated.
