Opponent didnt load, only i had checkmark, but lost elo and was queue penalized

I had the checkmark, was waiting on the loading screen for around 4 minutes.

Eventually i decided to do alt-f4, to find another game,

I lost elo + i was penalized in the queue for 8 mins.

This should not be penalized if i have been waiting for several long minutes in the black screen.

I had loaded, it was the opponent who hadnt, and i had waited for a long time, at least 4 mins
