Kicked from Ranked for Failing to Select a Champion (10 seconds left on the timer)

Hi. I was just kicked from a ranked match while the clock was still counting down. In fact, after I had been kicked to the homepage I heard the countdown ticks several seconds later.

Circumstances:

1. Last pick
2. Had been tabbing to other pages off and on through the selection
3. Had received a "disconnected from PVP chat" notification about 90 seconds prior. Despite that, I saw each champ as they were selected, I could read my team chat, and had even participated in chat etc after that notification.

Unusual circumstances, but sucky since it was ranked :/
