Orianna Shield glitch

Well after looking in the video it seems like I tried to put the ball on Pantheon and then it collided with Braums' shield I don't know if it was intended that the ball would teleport back to Orianna but if it is intended i think there should be atleast a 1s cooldown on ult to prevent this kind of stuff. Also in my opinion it should just stop its movement instead of teleporting back to Orianna.

would love to see something done about it!
