azir ult glitches

[GAMEPLAY] I do not know if other people are having this issue, but I have been finding that if you lock someone against a wall, or in a certain area with Azir's ulti, that they can dash through/over the wall when they shouldn't be able to. I trapped several gnars in the wolf camp, but they can jump over the wall. Also I've noticed that if lee casts his q and it hits you before you throw the wall up, he can dash through it.
