An interesting Yuumi W/Lee Sin ult interaction

The other day I had a Lee Sin pull a solo gank because my ADC was low on HP and he thought he could clean up. So I drop heal on ADC then hop off to proc shield. Lee Sin drops his combo, realizes he's fucked up and doesn't have the damage to finish and uses his ult for a knockback. I get the shield, then press W on Kai'sa who's now flying backward from being roundhouse kicked silly. I reach Kai'sa right as the displacement ends, and get knocked up upon touching her model, stopping the dash.

Coding wise that makes sense, but practically speaking it makes no sense for that to count as being "hit" by the flying Kai'sa. I was behind the projectile that "struck" me.

Anyways i'm not salty about it or anything, and it's not exactly a bug, I just wanted to get that out there that this exists.
