Paralytic Spores (Medjay Predasite) does not apply to Demolysts

[Vthor]

"Paralytic Spores -  Charge an enemy within 30m dealing 160 damage and releasing spores that stun enemies within 16m for 3s, leaving them open to Finisher attacks."

It works as intended for ordinary enemies, however for Demolysts it does not. Despite the blue highlight applied to Demolysts when Paralytic Spores are triggered by the Medjay. 

Is this intended or not?

My basis is how finishers still apply with other mods/weapons (ie: Sleep status and Dizzying Rounds) against the Demolysts.

How about for this mod's case?

An official comment on this mod's status would help.

 

Thanks
