a bug with disconnection for inactivity

so, i had a normal draft lobby recently, as usually, since that lute's prison island introduction, with trolls and stuff, the last pick picked janna when we had a support morgana and needed a jungler, i dodged, but accidentally did it too late, so i unknowingly went into the game and connected only at ~18 minute or so when i restarted the client. so, i briefly spoke with my team and thought to join them since we had a chance to win regardless, but i was hit by the bug, i was disconnected again, for inactivity (!) i.e. it counted as inactivity that time when i was already disconnected and when i connected it disconnected me for inactivity again after less than 30 seconds. i think it shouldn't work that way and i guess it's not how it's intended so i post it in this section. i connected again and we won btw, still one shouldn't be disconnected for inactivity again when they just connected after a prolonged disconnection, it sets their team even further back and makes no sense
