[CLIENT] Glitch when trading champions and someone leaves champ select

Pretty much what the title says. In the client, when I was in champion selection, my friend wanted to trade with me. I didn't have time to accept before someone in the game left the lobby, so the game was cancelled. However, I was stuck in a weird state where I couldn't interact with anything in my client and had to wait a couple seconds before the trade timer ended and finally I was returned to the menu. I don't know if this can be reproduced successfully but if you want to test it it's pretty easy: just offer a trade and someone leaves champ select. I would have an image showing my client but unfortunately I copied something else to my clipboard.
