[Champion] Ahri's Ult and Entering a location without Vision

When you don't have vision of an object when landing, and you land within a corner, or otherwise edge of an area, before vision kicks in. Ahri's R will fail to hit local targets. I've noticed this behavior before but thought nothing of it. It's so rare to come across in a live game that. a Ward usually guaranteed a hit on the side with a ward, but without it it was hit or miss.

For Reproduction, Maneuver to where a charge of Ahri's Ult will land just barely on the opposing side of the wall, it may take a few tries to get the positioning right, see accompanying video.

The expected result is of course, for her bolts to auto target to the 3 nearby dummies, players or jungle monsters.

The observed result, is Ahri lands and either some or none of the targets that are close enough will be hit.

I've been able to reproduce this on any wall i can dash over, so it has something to do with path finding and vision, probably not an easy fix if the initial los is blocked by the navmesh.... Though if this were true, i should of been able to hit the dummies directly away from the wall... Very Curious. Perhaps the movement update is done before the vision update? so the second i land the vision update hasn't occurred so i don't see those units, and my R isn't cast upon them?
