Champ select locks out if player is in summoner icon selection when accepting game

I was in summoner icon selection screen, and the client popped the notification to accept a game. I clicked the "accept" button, and got the sound effect, but none of the visuals for some reason. I was also able to repeat the sound effect by clicking the "accept" button multiple times, which also made me think it wasn't allowing me to accept.

After this, I did get into champ select, but it was from a spectator view, like what happens when the spectator buffer hasn't gone far enough to let you view the game itself. All of the bans and picks were empty, although my summoner name was highlighted like normal. The screen had a "quit spectating" button at the bottom of the screen. As you might expect, I wasn't allowed to submit a champion pick, so I was unable to select a champion, and the queue was dodged automatically after I didn't select a champion in time.
