> What this does is:
> - Adds a button to hide all current players on the page, but doesn't touch the C++ side to actually delete those players.
> - After a player is hidden, new logs for that player will be dropped and will not resurrect any hidden players.
> - If a user refreshes the media-internals page, or open a new one, we'll get all players back.
