Stadium doesn't rematch after an AFK player got kicked

Im my Stadium match I got a Juno AFK since sec 1 : no champ select, no buying session, no movement. She got kicked for inactivity after 2min and 35 sec. But it still counted as a lose and we lost ranking points. How is this fair. It seems pretty obvious the match should be aborted and do not count, as this was not a mid match leaver situation.
