Item models in resource packs that reference textures generated by paletted permutations are considered undeclared

[imIrony]

This is the item model for diamond_boots_amethyst_trim

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "minecraft:item/diamond_boots",
    "layer1": "minecraft:trims/items/boots_trim_amethyst"
  }
}

minecraft:trims/items/boots_trim_amethyst is considered undeclared although the texture is being dynamically generated in block atlas.
