[Client] Client Does Not Load Champion Select After Accepting Match

This is a fairly ironic bug. If one attempts to leave the queue before a match is made, and is prevented from leaving the queue because the match has been made, but then joins the match, the client returns to a grayed-out main page for several seconds. Attempting to enter a new queue redirects to champion select for said match, which proceeds normally.

1. Join a queue for a normal match (observed on Ranked Solo Queue and ARAM queues).
2. This is basically impossible to time, but attempt to exit the queue with the "Cancel from Queue" button right before the match is created.
3. Accept the invitation to the match.
4. The client should become gray for up to a minute before returning to the main page. Champion select does not come up even though the match was accepted.
5. Attempt to enter a new queue for a normal match.
6. The client should immediately disallow you from entering the new queue and redirect to champion select for the first match.
7. Champion select and the match should proceed normally from that point forward. Performance did not seem to be affected any other way.

This has happened to me twice by accident, and I am assuming that it is an unintentional bug. I have not attempted to recreate it to date, but video will be uploaded if it happens and can be caught.
