Baby Humanoid's leggings model's UV doesn't have correct mapping

Whilst adding equipment support for baby humanoid models in a resourcepack, I realized a few pixels weren’t really supposed to be mapped like that. Some parts of the top part’s pixels were on the sides, some sides do not line up with the top pixels at all due to stretching.

Steps to reproduce the issue

/summon zombie ~ ~ ~ {IsBaby:1,NoAI:1b,equipment:{head:{id:acacia_button},legs:{id:iron_leggings}}}

• use the resourcepack provided

Expected result

The pixels on the texture are mapped to leggings correctly, not sharing pixels between faces or stretched.

Actual result

UV is stretched and not done correctly
