"Shooting Stars" bug [fly into space]

Ive posted this bug a while ago and it happened multiple times to me. I dont really know if you actually saw my bug report but Im just posting it again to make sure that you actually see it.

This bug has to do with Galios knockup from his 'e" and tahm kenchs ultimate. So what happened was that I casted my ultimate with tahm kench but at the same time Galios attack interfered. Under normal circumstances I was either suppose to successfuly ult to another location if its not interrupted by an attack or its suppose to cancel if my channeling was interupted. However, as you can see somehow my ultimate still registered to be activated but because I was hit by galios "e" simultaneously, I teleported deep into outer space becoming invisible. That was probably the highest knockup ever recorded but then I somehow fell back down safely.
