[CLIENT] Apparently you can accept certain game invites while the lobby of a ranked game

I couldn't catch a screenshot of it, but apparently you can accept game invites from inside ranked lobby. Out of curiosity, I clicked the accept button which caused my client to freeze. The champion pick countdown timer continued running until it reached zero, and the client didn't do anything after that. I had to restart my client after that, at which point the 5 minute penalty was still applied to me.

Can't really find any steps to repro
