Put the summary of the bug you're having here

What I expected to happen was...:
Potions and potion effects in the creative and survival inventories would render normally.

What actually happened was...:
Creative: When under a potion effect, when holding a potion with your mouse the effect box on the left side of the inventory GUI turns gray.
Survival: When under a potion effect in inventory mode, the effect box is gray, however when holding a potion the box is normal, so the bug is inverted between gamemodes.

Steps to Reproduce:
1. Obtain a potion
2. Drink a potion
3. Go into inventory and pick up a potion
4. Watch as the box is turned gray
5. Go into survival and repeat; the bug is inverted
