A weird Conqueror "bug"

So I know the Conqueror keystone is broken as all hell, but noticed something strange with it and Malzahar.

So every damaging spell that hits is supposed to give you stacks of Conqueror, but for some reason Malzahar's voidlings dont stack it at all, this doesn't really seem intended at all, seeing as other champions that summon things can use those to stack Conqueror (Zyra's Plants, Heimer's Turrets, etc)

Couple other things which are probably intended but wanted to note. If you refresh your E with your Q you only get stacks for the Q. If your E spreads to another champion you also dont get extra stacks. Like I said, these seem intended but wanted to note them.

I would really like to get an answer on the Voidling thing, that doesn't seem intended at all, if their first hit would at least proc a single Conqueror stack even that would be better than this. As of right now Malzahar does lack a lot of sustain, which is a major downside to a champion that also lacks any form of escape (aside from a flash, and mid to late game when you have a Rylai's) and Conqueror paired with the full Precision tree would solve the lack of sustain, at least early game.

This post might not matter much, because I'm expecting Conqueror to either get a full rework again, or get nerfed into the ground, but until then could the Voidling thing be looked into, because that doesnt seem intended at all, it is a damaging spell after all.

I tested this in a game and with the Practice too, with all champions listed in this post by the way, Both Zyra and Heimer stack on their plants/turrets, Malzahar recieves no stacks from his voidlings
