[Bug Report] Sell Eats Items

Minecraft Username: Jrg5978

Brief Description: Using /sell hand *number* with more than one stack of the item will take away the stack that you are holding without giving you money, (unless you are holding the first stack of items)

Instructions:
1. Get more than a stack of items
2. Hold a stack other than the first
3. Type /sell hand *number* and the stack you are holding will disappear and it will take items from your first stack.


How many times did you recreate this bug?: Multiple

Result: Lose a whole stack of items and didn't get money for it

Expected Result: Not to lose your items.

Evidence:

Video Explanation:
1. I type /bal and it shows that I have $7385.50
2. I type /sell hand 5 while holding my second stack. Notice that the first stack of 64 goes down to 59 but the whole entire stack I was holding disappears.
3. I type /bal and it only gave me 25 cents, even though it took my whole other stack of 30 netherrack as well, proving that those blocks just disappeared.
4. I click around to show it isnt glitched somewhere and relog (I cut my login screen out of the video so I don't advertise)
5. Upon relogging the items are still gone.
6. I do the same thing all over again and my whole second stack of nether rack vanishes without a trace again.

If you have any questions about the video or anything just ask me. This is a weird bug that could have some harmful potential so I hope that you look into this and that there is an easy fix.
