Lightning Rods do not follow the same "textures"/"carried_textures" behaviour as other blocks

when customising textures for Lightning rods (Waxed and Unwaxed, in all Oxidisation states) the blocks.json file ignores any “carried_textures” entries and only uses entries defined in “textures”.
Additionally when using “textures” to define the faces of the lightning rod, the game uses “up” as the carried texture on all faces and “down” as the in-world texture for all faces. This also leaves the side faces (defined by using either “side” or compass directions) as being unused/not visible on either rendering of the block model.

STEPS TO REPRODUCE;

1. create a custom resource pack

2. inside blocks.json create entries such as;

   "waxed_lightning_rod": {
       "carried_textures": {
           "up": "red_concrete",
           "side": "pink_concrete",
           "down": "blue_concrete"
       }
   },
   "lightning_rod": {
       "textures": {
           "up": "red_concrete",
           "side": "pink_concrete",
           "down": "blue_concrete"
       }
   }

3. open a world with the resource pack and obtain a waxed and unwaxed lightning rod

EXPECTED RESULT;

The Waxed lightning rod is coloured red and pink inside the inventory, but regularly textured placed in the world.
The Unwaxed lightning rod is coloured red and pink placed in the world, but regularly textured inside the inventory.

ACTUAL RESULT;

The Waxed lightning rod is regularly textured both inside the inventory and placed in the world,
The Unwaxed lightning rod is coloured only red inside the inventory, and is coloured only blue placed in the world - with the colour pink not visible in either rendering.
