Hi,
I'm creating a simple polygon svg shape, and using it to mask an image using the clip-path:url(#id) method. I'm then trying to animate this using GSAP. This works fine, except in FireFox, where no animation occurs. This can be viewed at this codepen: http://codepen.io/rorytawn/pen/OVeWNB. All I'm trying to animate is simple 2D transforms like x and scale.
I know FireFox has some issues with clip-path, so I tried animating the same shape, when it is not used as a mask, and that works fine in FireFox. So the issue is something to do with animating the svg when it is assigned to cli
