When a spawn egg has custom entity data, using it on an adult mob no longer applies that data to the summoned baby mob.

To reproduce

1. Get a custom spawn egg

   /give @s minecraft:husk_spawn_egg[minecraft:entity_data={id:"minecraft:husk",HasVisualFire:1,NoAI:1b}] 

2. Spawn an adult husk
3. Use the spawn egg on the adult mob
4. Check if the baby mob has the HasVisualFire and/or NoAI tags:

   /data get entity @n[type=minecraft:husk,nbt={IsBaby:1b}]
   

Expected behavior: The tags are applied to the baby as well.

Actual behavior: The custom tags are not applied to the baby.
