Stacked potions won't be stacked anymore after you drop them on the ground

Potions that are stacked before dropping them(not throwing)won't be stacked after picking them up again

What I expected to happen was that after picking the potions up ,they would've been still stacked

What actually happened was that after picking them up all the potions we're sepretaly in my inventory.

To create the bug you need to:
1. drop potions that are stacked by using mcedit or a /replace command
2. pick them up
