Creeper confetti feature not working with modded creeper variants

[IdkWhatNameThingyToPut]

Even though they're not vanilla mobs I thought I would still make a post here about it because it would be a rlly cool feature to have, I'm not sure if it's a straight up bug and they're supposed to work with the creeper confetti feature or not, if not I guess this can be taken as a compatibility/feature request idk

Same thing with specialmobs too
