Netherite boots model don't matches their item sprites

What I expected:

The model of netherite boots' taller part should be behind the main part.

What it turns out:

The model of netherite boots' taller part is flipped horizontally.

How to reproduce:

1. Craft two pairs of netherite boots. or give yourself one using the /give command.
2. Place one pair to an armor stand.
