Auto-queue when someone leaves

When you’re in a group and in the role select screen in comp role queue and if all the people who are not ready leave, it auto-queues and it stays queued if someone ready leaves. A friend was grabbing a drink and i realized i should restart my computer, so i closed my game and it started queue for him and another friend when i left because they were both ready, the other one tried to leave the group hoping it would stop the queue as the afk person was party leader. Unfortunately the queue continued and they were placed in a match and received a loss for afk. Seems like a bit of an oversight or glitch.
