GSAP unable to animate clip-path: polygon with calc percent + px units

[bradwoods.io]

I've seen sandboxes of GSAP animating polygon but none with calc using percent + px units. Does anyone know if I'm implementing this incorrectly or if not, a workaround for this? Sandbox:

That's because your starting and ending strings have different amounts of numbers and are formatted differently, thus the complex string animation can't function the way you expected. 

 

There are two pretty easy solutions: 

 

1) Just make sure the start/end strings have matching formatting and quantity of numbers:

2) Use a CSS variable to simplify things:

Does that clear things up?
