Zombified Piglin chicken jockey does not drop Lava Chicken music disc

Chicken jockeys with zombies (and I think zombie villagers and husks, too, though I’m not completely sure) drop a Lava Chicken music disc when you kill the zombie on top. However this does not work with zombified piglin chicken jockeys you can rarely encounter in the nether.

To test it, summon a regular chicken jockey with this command and kill the zombie:

/summon chicken ~ ~ ~ {Passengers:[{id:"minecraft:zombie",IsBaby:1}]}

and then summon a zombified piglin chicken jockey with this command and kill the zombified piglin:

/summon chicken ~ ~ ~ {Passengers:[{id:"minecraft:zombified_piglin",IsBaby:1}]}

Expected result: Lava Chicken music disc drops

Observed result: No disc drops
