Wolf pack + Cast on Minion Death (not working)

Wolf pack is a minion gem, is supportable by minion support gems, and when these wolfs die, trigger HeartBound loop. They do not however count for Cast on Minion Death for some reason.

I currently use Wolf pack (Minion instability, Feeding Frenzy I, Infernal Legion III, Minion Mastery) to proc HeartBound Loop self damage to stack up Iron Ward. This all works correctly.

I just tried to use Cast on Minion Death to cast Profane Ritual but CoMD does not gain energy from the minions dying.

I'm not sure if its a bug or if something was overlooked, but I'd like to see this fixed. All the ways I can see this, CoMD+WP should work.

They are tagged as persistent so this should work, perhaps the respawn is to quick but it should work

can confirm, presently wolves do not count for COMD. Possibly intended nerf?
