Anivia - Use Wall to Stun the Poro King [Gameplay]

I ran into this a little bit ago. When playing Anivia in the Poro King game mode, you can stun the poro king by placing the wall on top of it. If you put the wall in the very center of the poro king if just kind of glitches out for the duration of the wall. I figured this wasnt supposed to be happening. Hah!
