[Gameplay] Kalista bugging with nautilus hook

Hey,

I was playing a game earlier going full AP nautilus (Lada-deee Lada-duu) and I went in for the hook against Kalista. I hit her, but at the same time she triggered her passive to jump away. Her jump seemed to ignore the CC from the hook, like Ezreal's Arcane Shift does to Blitzcrank hook. However this seems a bit overpowered as he already has a lot of mobility and can completely ignore my only way of engage pre 6.
