[Gameplay] Auto Attack through Guardian Angel respawn.

I was in a game, and during a team fight, the enemy team's Kalista died. She had guardian angel, and when she went down the swirling cloud appeared above her body, but there was a second version of her, standing over her body that continued to attack and deal damage throughout the entire Guardian Angel respawn animation. If it makes a difference, this occured just before 49 minutes in the game linked above.
