Gameplay Bug Ezreal's E

while playing ezreal there is a strange interaction with his e arcane shift and volibears q rolling thunder. if you use ezreal e when voli is running toward u with his q and u complete the cast of e volibear still throws you backward even though you are out of range of his ability. the result i expected would be similar to what happens with any other displacement such as a blitzcrank hook which is your blink cancels the displacement
