GP can orange out of Yasuo's ult

Pretty much GP has to just eat oranges and he will leave Yasuo's ultimate all together, though I'm not quite sure if it negates the damage on the ult as well. I saw this when fighting against GP earlier as Yas where he immediately escaped my ult even though it should have held him in the spot for the duration.

There might also be the bug where GP can remove the ability to allow Yasuo to ult onto him if GP eats an orange before Yas uses the ult, but I'm not sure (Saw it happen a few times in games before today, but it could have been me failing to hit R in time while slow rolling)

Edit: I got a downvote for saying what occurred, but shouldn't actually occur. Yas's combo is all knockup, which should make it not be ended immediately by GP's orange....
