[CLIENT] Poro King Games Incorrectly Registers Game Abandonment During Champion Select

The poro king games seem to incorrectly register me abandoning games when I am not doing so. It has happened to me twice, resulting in long temporary bans. It seems to have something to do with being in the masteries window after the ban phase after preselecting a champion - I have been adjusting my masteries both times it has happened. It may be caused by another playing leaving at a particular time, or perhaps it's registering me as not selecting a champion after the ban phase.

If I had to guess at reproduction steps: preselect champion, pick ban, see each teams bans, do not lock selection (?), and be adjusting masteries when another player leaves. I can't verify this, because I have a temp leaver ban from this bug, and I wouldn't want another one.

It may or may not be relevant, but my chat is disconnected.
