Smite Fizz bug [Gameplay]

If Fizz smites a monster camp with Rangers Trailblazer while he is untargetable in his Playful/trickster the mana and health return will not occur.

100% reproducible Steps:

1: Buy Rangers Trailblazer 2. Use first cast of Playful/Trickster 3. Smite monster camp.

I don't have any screenshots but I discovered it while playing as JG fizz earlier taday. Went into a custom game and I could reproduce the bug every time.
