Quitting during POTG causes penalty

I keep getting EXP penalized for leaving when I don’t want to watch someone press Q and the counter keeps growing every time I forget about this bug and do it while penilized. My guess is that effects Endorsement lvl as well since it counts as leaving early.
I’ve found some old topics where the Blizz reps response is that it’s safe to leave after the victory/defeat text pops up on the screen, so before POTG, which means it’s not “working as intended” (recognize the “iconic” canned response?).
Either fix it or remove it, ACTIVISION.

hmmmm.
it never effected me.
