[gameplay] Sion ult bug with Lulu

Yesterday, a Sion ulted me while I was playing Lulu. Before he hit me, I cast whismsey on him, hoping to be slammed into by a squirrel. When he hit me, he stopped and immediately became a squirrel. I took no damage and was not CC'd in any way. I ran away from squirrel Sion and was probably 1000 units away from him by the time he stopped being a squirrel. As soon as he transformed back, I was knocked up, then stunned and I took his ult damage.
