Issue: The Burning Baby Zombies option is forced upon baby husks. Not sure if this was intended but to me it feels out of place with vanilla since husks don't burn in daylight at all. I think it should have the option to choose if baby husks and/or zombies burn.

Steps to reproduce:

1. find a baby zombie or use /summon minecraft:husk ~ ~ ~+5 {IsBaby:1} while daytime (sky above husk
2. watch it burn

False alarm. Found out the mod Vanilla Tweaks has this option as well. That was the cause. Closing issue.
