[Client] Cancelling queue messes up chat

Can't seem to find this bug being posted, although its happened to my friends and I multiple times since the last patch.

Steps to reproduce:

• User creates a normal, blind pick game with party
• User invites between 1-4 friends to play
• User starts search
• User cancels search At this point, the party chat is unresponsive, and other chats with people scrolls up after each message.
