[GAMEPLAY] Can click on enemy thresh's lantern while in grave's smoke

Was playing as Ashe in ARAM. Thresh threw out his lantern. I walked into grave's smoke. I mouse hovered over thresh's lantern. It displayed the blue arrows back to thresh and show's thresh's location (even though i was standing in the smoke and thresh was standing in a bush. Thresh's lantern was clickable (did not manage to click on it in time).
I'll update if I manage to reproduce it and get a video. (None of my friends are online at the moment to test this out)
