Steps to reproduce the bug

1. Start playing a video
2. Pause the video (doesn't matter how it's done, can be with the pause button or externally)
3. Use either a keyboard's space button or a bluetooth earpiece to resume the playback.

I think the problem is that hideControls isn't called when using the media keys

Actual behavior

The play button stays visible.

Expected behavior

The play button should hide, like when you tap the button manually.

Device info

Not applicable, happens on all the devices I've tested.
