Poppy Passive Interaction with Plants [Bug] - GAMEPLAY

Poppy's passive, Iron Ambassador, doesn't automatically bounce back to her upon killing the new plants in the jungle like it should. It bounces back when killing all other forms of units (minions, champions, wards, Jhin traps, Teemo shrooms, etc), so I figured the shield not bouncing back on the jungle plants must be a bug. This happens with any skin and any plant location. PLEASE CHECK THIS OUT RIOT!! This does affect Poppy's game play!
