[Gameplay] Suppression on Kallista

During multiple matches so far I have encountered this bug. When I play Malzahar and use my ult on a Kallista, she is still able to auto-attack, making her side-step animation, but not moving. This occured with a Warwick ult being used on her during on of my recent games as well. I am not sure if this happens every time you suppress Kallista, or if it only occurs if you do it during a certain part of the animation, but this occured more than once throughout each game.
