Brand Ult not affected by Yasuo Windwall

Bug: Brand Ultimate is unaffected by Yasuo Windwall. [Gameplay Bug] If a Yasuo uses windwall before the brand uses ultimate the windwall will stop the ultimate, however if the Yasuo uses windwall after the Brand ultimate is already following the Yasuo the windwall is rendered ineffective. This bug can be recreated every single time you windwall after the ultimate is in motion and it isn't affected by any area of the map it will happen anywhere. I have recreated this over 40 times in a custom game with a friend. I have also attached a video clip showing this happening in game.

Kind Regards,
