This is yet another reason why you shouldn't use animations in CSS3 and should do them in JavaScript. I honestly don't understand how behavior (which is what animations are) got baked into a declarative style language. Layout (which is also behavior if the layout changes with the dimensions of the viewport) and animations are two things that need to be removed from CSS and implemented in JavaScript.

Well, "should" isn't a great word in this context. Yes, animations probably should be in JavaScript, but you probably shouldn't do them in JavaScript right now as they won't be hardware accelerated. The reason it works well in CSS is that you're setting a property and letting native code do the rest, whereas in JS you need to set a property in each requestAnimationFrame() call. Not good.
