Teamkilling as Ekko [Gameplay]

While playing ekko on Twisted Tree line at the end of the game, a tower killed my ally poppy after I had ulted to reset tower aggro. The reward for the kill was given to me as well as the bounty gold on my ally poppy's head. Match History

edit: You can see poppy's death to ekko at the very end in the blue kill graph on the team gold advantage graph.
