( Gameplay ) Fizz (e) bug where blitzcrank (e) would displace fizz in his (e) animation

Was playing a fizz game vs a blitzcrank and when i would use fizz e ( untargetable ) to escape blitz he would e ( knockup empowered basic ) which would displace me out of my e animation. At first i thought that it was that he ( blitzcrank ) would instantly e me instantly after my e animation to just knock me up but after seeing it happen time and time again im sure that i was being displaced during animation.
