The right and left wings of a bee cannot be independently retextured, despite the texture including two wings

(This issue first appeared in the snapshot Minecraft 19w34a)
The right and left wings of a been cannot be independently retextured from one another, making them always look the same. This is limiting to the player's resource pack creativity and freedom to edit the texture.
This issue is especially interesting for two reasons; 1. The antenna on the same model can be retextured independently, and 2. The textures for the bee actually includes a right and left wing texture, but the right one goes unused.

Steps to Reproduce:

1. Download and apply the following resource pack:

1. Spawn/Summon a bee

Observed Behavior:

Both of the bee's wings will look entirely red, despite the player seemingly only modifying the wing in the UV map.

Expected Result:

Only the left wing of the bee would be altered, since that is what the player intended to change. The current behavior is unexpected and not resource pack friendly.

Code Analysis:

Here inside BeeModel, you can see that the wings are mapped to the same area:

Notes:

As noted in the second paragraph of the issue, the texture includes two wings. Only the top is used:
