[2020] Tonkor Self Damage Bug?

Can you post screenshots or video about your weapon and warframe loadout?  I'm not sure how you would get this since the Tonkor has a "safety fuse" that prevents it exploding until it's traveled a minimum distance.

Not able to make it hit me midair, can get it quite reliably by wall hopping though.  Thanks for the mind-bending bug report 😄
