The problem is that getAnimatedStyleForRenderer() can return a null style, and is not expected to.

Created attachment 28504 [details] Patch, changelog A testcase is hard, because it requires fast clicking.

Comment on attachment 28504 [details] Patch, changelog Seems to me we could have just done this in AnimationControllerPrivate::getAnimatedStyleForRenderer and avoided passing that renderer down all those levels. Would that be better?

Darin: I did it this way to avoid another RefPtr<RenderStyle> in getAnimatedStyleForRenderer(). But I can do it that way if you like.
