Describe the bug

Videos go to black when resetting the transition timer.

To Reproduce

When I take the example:

https://codepen.io/martinlaxenaire/pen/ZEBNyMV

and change the library version to be > 8.1.2 e.g. 8.1.6

like this:
https://codepen.io/rogierhofboer/pen/ZEgWMrW

the videos go to black when the transition timer is reset.

Expected behavior
The video should stay visible.

Note:
On an Android Webview, also the images go to black after the transition. So it seems timing related.
