Leather armor does not render properly on paper doll when using higher anti-aliasing

When wearing leather armor, the paper doll in the top left corner embeds it into your current skin instead of showing it as a separate texture.

Steps to Reproduce:

1. Load a world
2. Make sure "Hide Paper Doll" is turned off
3. Increase the anti-aliasing
4. Equip leather armor
5. Start flying to see the paper doll
