I'm trying to get this tween to work with an eventListener, and it works fine if I pull it out of it, but as soon as it's back in the event listener, nothing happens. I've also tried doing it with jquery and using .play() and .pause() and I am getting the same issue. I also tried setting the event listener to the clippath itself, rather than the circle, and no joy. No idea what's wrong here! I'm working directly off this other codepen and it works fine there. http://codepen.io/rorytawn/pen/OVeWNB
