Auto Hide Player Pop-ups
This might be an issue with Firefox so I'm not sure if it's a technical issue or a suggestion.
When I click the volume or gear icons in the player interface I have to click them again to hide them. If I don't do this the pop-ups remain even after the interface fades away. Kinda annoying.
@pleco_breeder spent some time helping me to work out this issue and it only happens in fullscreen. It just adds an extra step, nothing's broken, but obviously this isn't intended to happen.
Turns out this is a technical issue, I hope the @administrators pass it along.
