What I expected to happen was nothing

What actually happened was the potion display was messed up

Steps to Reproduce:
1. Have any potion on
2. Get a piece of damaged armor (go on survival mode and spawn a zombie etc. then change back)
3. Hold the damaged armor with the potion effect on the Inventory GUI
(Please note, the visual effects on the potion display may vary depending on your Resource Pack,) [on default it's black, on mine it's white]
