OH! ANIMATOR ClipPath

Hi Oooh Boi!

Just experimenting with OH! ANIMATOR. Great stuff!
I’m trying to animate ClipPath but no luck.
Nothing happens while other animations are working.

I use this property for From:
clip-path: polygon(0 0, 0 0, 0 100%, 0% 100%);
and for To:
clip-path: polygon(0 0, 100% 0, 100% 100%, 0 100%);

I’m trying to recreate reveal animation.

Any suggestions? Thanks!
