Hello,
When switching to pulse animation, the button background seems very buggy. Does not look good at all.
I've tested it (with cleared caches) on chrome, edge and firefox. Problem is visible on all of those browsers.
Please see this video (where I show it on chrome and then on edge browser): https://tinyurl.com/y2hj555f
(on iphone it's even worse: the blue square is not animated)
