Inventory player model reacts to light level

The bug

The player model in the inventory (Both survival and creative) reacts to light level just like the player in the game. This means that when it's dark, the model in your inventory becomes dark as well.

 

How to reproduce

Open the inventory in any light level you are currently standing in. Then find a contrasting light level to stand in and open the inventory again. See how the model in the inventory either gets darker or brighter.
