Playing embedded video in chat will inhibit screensaver indefinitely

### Steps to reproduce

1. Set your display power management timeout to 1 minute
2. Launch Element
3. Find and play any embedded video

### Outcome

#### What did you expect?

I expect display power savings to kick in one minute after I either pause the video or watch till the end.

#### What happened instead?

At this point it does not matter, whether you hit pause or watch till the end: display power saving will never kick in. Not until the app is terminated.
