[Bug] Vel'Koz's E and Yasuo's W interaction!

Hey guys, just noticed that Yasuo's W blocks the projectile and animation from Vel'Koz's E but the knock up still happens on the targeted area past the wall. In other words, Vel can knock up someone on the other side of Yasuo's Wind Wall even if the E projectile is blocked by the wall.

Don't know if this is something everyone knows, just thought I'd bring it to someones attention.
