MC-195139Zoglin "IsBaby" entity tag cannot be changed from true to false (1b to 0b) with /data
The bug
Despite MC-65953 being fixed, the IsBaby entity tag for zoglins cannot be changed from true to false (or 1b to 0b) with /data.
Can confirm in 21w07a. Here are some steps to reproduce this issue:
To reproduce:
- Summon a baby zoglin
/summon zoglin ~ ~ ~ {IsBaby:1b} - Run the /data command:
/data merge entity @e[type=zoglin,limit=1,sort=nearest] {IsBaby:0b}→
"Modified entity data of Zoglin" is shown in chat but the mob still remains as a zoglin piglet.

Code analysis (Yarn mappings)
The following code in the ZoglinEntity class manages the babiness of zoglins:
Notice that the zoglin becomes a baby if the IsBaby field within entity NBT is true. There is no behavior for making the zoglin not a baby if the IsBaby field is false.
Compare to the same methods in other entities with a boolean babiness status (zombies and piglins), where the IsBaby field controls babiness regardless of being true or false:
