Baby Hoglins are unable to be summoned via command

Whenever I do "/summon minecraft:hoglin ~ ~ ~ {IsBaby:1}", it summons an adult Hoglin rather than a baby. However, when I do "/summon minecraft:piglin ~ ~ ~ {IsBaby:1}", I get a baby Piglin (as intended).

I don't know if this is like attempting to summon baby animals (i.e. "/summon minecraft:pig ~ ~ ~ {IsBaby:1}" and getting an adult pig), but still, it just doesn't feel correct.

I tried this same command with Zoglins and I, as intended, get a baby Zoglin.

This is probably intended, but I thought I'd point it out
