Aatrox q bug (Gameplay)

Aatrox q has so many issues such as failing to knock enemies up or it being canceled upon descent but this certainly is an interesting one. If Aatrox takes thresh lantern at max range and tries to immediately q after making it to thresh he will fly directly upward and be unable to move, not to mention it puts his q on cd. It is also really easy to reproduce. Simply take a max range thresh lantern and press q upon making it to thresh. Please fixerino riot
