[Champ Select] Client timer errs when LoL client is not in focus

If I have another window open(aka a browser, maybe reading LoL boards or champ builds), and have that browser in focus - and the LoL client out of focus - during champ select, the ban/pick timer will bug out and ban me. This has never once happened if I leave focus on the client during champ select, and only occurs with the new champ select during Normal Draft Pick. My connection is excellent. I do not lag during games, or in any other game.
