King of The Mists stands still and gets invulnerable

When the King of the Mists -not the one that is fought in the Stronghold - gets knocked back far into the Darkness, it seems that he can get permanent stunlocked and he doesnt do anything and cant be damaged anymore, even when you unlock the area where he got knocked back.

The bug might be recreated by using some kind of knockkback e.g The Siege Small Cluster jewel that gives permanently knockback to enemies.
