Lux Ulting while knocked up

When Lux is ulting and and is knocked up mid animation, Lux's ult will do zero damage. Then animation will still go and the cool down will still be started. This is confusing and needs to be updated/fixed. Either make the animation not go, or let the damage still go off as seen with ultimates like ezreal's Trueshot Barrage While ezreal is ulting, and is knocked up, his ultimate animation AND damage still goes. These inconsistencies should not exist. This is a minor bug? Mistake? Confusion? but as a lux main, it would be nice to get it cleaned up. Thanks!
