[GAMEPLAY] Corki - if Morgana is in a bush and uses black shield you don't get any vision of her

I have been playing Corki in Hexakill and noticed that when you use his Phosphorus Bomb in brush where Morgana is hiding and Black Shielded you don't get vision of her. In the text description for Phosphorus Bomb it states that it reveals The Area as well as champions. Black shield is supposed to prevent disables but Phosphorus Bomb shouldn't be counting as a disable for it's ability to reveal champions. I only played on twisted treeline in Hexakill so I'm not sure if it does the same thing on Summoners Rift and I don't know if the same thing would happen if Morgana used black shield on another champion in a bush. It happened every time Morgana used black shield on herself while in brush.

You can recreate the bug by having Morgana go in a bush and black shield herself and then have corki use phosphorus bomb on the bush.
