[Invite Bug] Invite appears in Champion Select

Please fix this bug that not only makes me able to receive an invite in champion select, but also makes me able to click accept and thus makes me dodge the champion select.

Detailed description of what happened is below.

I was in my ranked promos Champion Select. We were in the banning phase, and I SOMEHOW got this invite from a friend/friend of friend (I couldn't remember which) to a normal game.

I hover my mouse over the accept button, and my mouse icon changed into a hand, indicating I can click it. My curiosity outweighs my worry of technically losing this promo match, and I pressed accept.

I'm still in champion select. Everyone left the room, however I'm still in the room. Strangely, the timer is still there and there is yet banning to do. The person who was banning did not select anything and thus after the timer ran out, the champion select disappeared. I was sent to the home screen of my League client, seemingly as if I dodged the match. I checked my ranked promotion score and indeed it marked an extra X as if I dodged and was counted as a lost.
