[GAMEPLAY] Stunning Rek'Sai in Her Burrowed Form Renders Her Immoblie if the Stunner Remains in Her Circle

This is a little hard to visualize and unfortunately I don't have a video. If you are in burrowed form as Rek'Sai and are stunned you are unable to knock-up the enemy or move towards the enemy long after the stun has ended if they remain in your circle. This has happened to me twice. The one I specifically remember is when I approached an Irelia in burrowed form. She dashed, stunned me, and stood next to me auto-attacking. Even after the stun had long been over I could not knock her up and couldn't move no matter how much I clicked on her. She remained in my circle the entire time which seems to be the problem.

Steps to reproduce. Approach an enemy champion as Rek'Sai in her burrowed form. Have the enemy stun her and have the enemy remain in her circle (of knock-up). After the stun duration has ended, as Rek'Sai, click on the enemy champion. Rek'Sai should do nothing and remain immobile.
