QOL fix for Lux's ult

There have been a few complaints on my subreddit about situations where Lux's ult appears to hit its target, yet doesn't do any damage whether it's a bug, or the misalignment of the laser particle with the hitbox.

In this scenario, Yasuo was rooted and his flow shield was down, and was dead center in the laser, but it had no effect at all. This is likely a bug.

The other video that popped up today:

This one is likely more of a clarity issue, as it appears that Nami is getting hit, but given that the laser particle effect isn't perfectly aligned with the hitbox given the game's camera angle, Nami is actually above the laser's hitbox.

My suggestion is to draw the laser's hitbox on the ground, visible only to Lux and in spectator mode/replays, so that we can easily determine if someone will, or should get hit by the laser, and then after that, figure out what is causing potential issues in cases where the target should get hit, but isn't taking any damage.
