Description Tyler Wilcock 2023-02-05 11:24:01 PST 
Given this sequence:

  1. Pause All Animations on the page
  2. Individually play a single animation, notice it is animating correctly.
  3. Scroll away from the animation such that it's off-screen
  4. Scroll back to the animation

Notice the animation is paused when it should be playing (because it's respecting the page state over its own state).
