[GAMEPLAY] LeBlanc R+R Autoattacking a Minion

On LeBlanc, casting Shadow of the Rose (LeBlanc's R+R) should summon a harmless duplicate. However in a recent game, my clone turned around and autoattacked a minion, doing full damage with that autoattack to it. I'm not sure if it was because the minion aggro'd to the clone, or if it lost sight of the champion it was chasing (Lux) but I don't believe that should happen.

I can try again on a day with more time to reproduce this bug.
