Hide OSD when entering PiP

[rechigo 364]

I have a minor annoyance/bug with the Emby app... When entering picture-in-picture via the OSD, the OSD stays on the screen for a couple seconds. I think the expected behavior here is the OSD is hidden as soon as Emby enters PiP so the user doesn't have their content obstructed

Video demonstrating behavior explained above
