Not exiting Queue after pressing the X

This happens ALL the time. When I click to exit out of game queue, it doesn't actually take me out of queue and keeps going.

As you can see in the video clip, my cursor clicked on the X and nothing happened. The client forced me to Deny the lobby that popped up. Denying once or twice isn't a big deal. But for someone who denies lobbies a lot the system starts punishing you by taking away LP for ranked games.

Please fix this bug.

Edit: Here is another bug where the video shows me quite clearly Accepting the Match, yet the client bugged and said I didn't accept the match

One or two of these won't penalize you. But when this happens 6 times in a row, then I will lose 10LP due to no error of my own.
