Accepting or declining the "Match Found" popup didn't result in the popup closing.

The popup opened once a match had been found, but when I clicked on "ACCEPT!", the popup did not disappear. The accept action was processed though; I could still hear the champion select begin in the background. I tried both the "ACCEPT!" and "DECLINE" buttons, but neither removed the popup, only activating their pressed action sound. I closed the client, probably shouldn't have so I could've seen how the bug reacted once I didn't select a champion. When I reopened the client and queued again, there were no issues. Lost one of my promo games from it.
