[GAMEPLAY] Shaco Bug Poro Toss while invisible

I'm experiencing a bug with shaco using the poro toss skill while invisible, wherein, shaco doesn't actually get teleported and instead the character actually disappears on screen (instead of becoming translucent).

Steps

1. Go invisible
2. Use poro toss
3. Activate poro toss teleport

This always happens whenever I try this.

EDIT: Tried it on custom game and it works somehow...
