the removed animation played when page state changed (document visibilitychange event)

[elvira1112]

Describe the bug:
I remove an animation, but it played when i trigger the document visibilitychange event.
I found that It doesn't remove the animation when i removed. And when it run into visibilitychange event, it played all of pause animation.

To Reproduce:

1. remove an animation
2. i slide my desktop on my mac, i guess switch tab also can trigger the bug. Anyway, to trigger the visibilitychange event.

Expected behavior:

1. my removed animation can not replay

Desktop:
browser chrome v73.0.3683.75

@juliangarnier @chrisbrown-io I think bug is still there, at least partially perhaps.

Steps to reproduce:

1. deactivate tab (so it would become document.visibilityState === 'hidden')
2. run myAnimation.pause() (while document.visibilityState === 'hidden')
3. get back to tab, so it would trigger visibilitychange event

Actual results:
Anime restores animations https://github.com/juliangarnier/anime/blob/3.2.0/src/index.js#L875 including those which were explicitly paused by user (in step 2)
