active potion in inventory render bug

What I expected to happen was...:
Normal rendering

What actually happened was...:
Fail at rendering active potions and when you hover over it with an item you see a square from the item

Steps to Reproduce:
1. Give yourself an effect like /effect @p 10 600
2. go to your inventory and select the potion tab
3. pickup an enchanted potion or item

Edit: no errors in development console
