[Client] Champ select music can play after champ select

(This is for Mac) I tested this twice, both custom games full of bots. What happened was once champ select was over and the 10 second countdown till the game starts finished the client switched form the client to league of legends, in this time (about 1-5 seconds) or for the first few seconds of the loading screen, if you click over to the client (to message a friend for example), the champion select music will start over and play the full loop (so about 1 minute) before stopping, regardless of if the game has stated or not.
