Illaoi can cast all abilities while getting knocked up

Hello, today i played ornn and for the first time in my life I thought man, this needs to be fixed.

Knock ups always were to one and only true cc that noone can stand against.

Well, Illaoi can. She can cast Q fully when she casts the Q even if she gets knock up'd instantly.

So she can even cast ult while getting knocked up and just "ignore" the knock up. (If it was only when she started ult before the knock up it would be okay but it isnt.)

Same for every single ability, either way she cancels the knock ups or she can just cast it through and still deal the dmg. I think this is really buggy cause this would make illaoi basicly CC immune or useless against her if she can still out-trade you while being cc'd
