[Bug - models] Undyed leather armor does not display correctly, with or without custom resourcepacks

[aidensings]

Describe the bug
The base of undyed leather armor appears entirely black, only the overlay shows. When dyed, the armor displays correctly.

Screenshots

The first image is vanilla textures, the second is using a Vanilla Tweaks resourcepack with the "no overlay" option.
In both, the zombie is wearing undyed helmet and chestplate, black dyed leggings, and yellow boots; the skeleton is wearing undyed helmet, leggings, and boots, and a pink chestplate. I am wearing entirely undyed leather armor.

(please complete the following information):

• Minecraft Version: 1.21.3, NeoForge
• EMF version: 2.3.0
• ETF version: 6.2.8

Additional context
No other mods are active to interfere.
