Match found bug in party

[gtfd]

When you queue as a party and find a match, if you leave the party while being assigned to a server, the person leaving the party will get inside a different match completely than the rest of the party, resulting in a 5v6 match for the party. The game did not start as you can leave without penalty immediately so i do not have a match id to share.
Once you find a match, it should not be possible to use the leave party button to avoid uncontrolled behavior

Just had this happen to me in a slightly different way (i think, i apologize if i'm hijacking):
I wasn't in a group on accident, so i cancelled a queue.

I joined up with party, we queue. I get in a game but they do not (seems to be from joining a party rather than leaving one). I got a message about teammate leaving or some such (i missed the text).

We get back to menu, i have the "rejoin" where "play" is, but my friend, as party leader, starts a queue (no rejoin for them). i accept; we get into a game and play. afterwards, i have a temporary ban for abandoning a match.

unfortunately i did not take any screenshots or anything because we actually got in and played. plus, this was all pretty fast (~1-2 minutes)
