[Client Bug] Login Music Keeps Playing After Login

It isn't a game-breaking bug or anything but I thought I might report it. Right after you enter your password and it says "logging in," if you minimized the client by clicking the league icon on the task bar and then open it again you will be logged in but the login music will still be playing. It doesn't happen that often (today is the first time it happened to me actually). Just thought I would let you know.
