Master Yi can stun people

Whenever Master Yi Qs, and you're standing near a wall, he plops out on the other side of you and makes it so you cannot move. This only happens if he Qs on you and when his Q finishes you are touching a wall or almost touching a wall. You have to either kill him or flash out to move again, or he has to move. I thought it wasn't worth mentioning but I've never noticed it until yesterday and it's happened three times since then so it's common enough and seems to be a new bug
