Bug: Summoned Armor Stand and Bugged Items

While I was playing around with the new Armor Stands I found out something interesting:

If you Summon an ArmorStand with a Item In its Hand and try to remove it using RMB you get an glitched Item in Return with a red 0 as Count number.

1. Summon an Armor Stand with an Item in its Hand
2. Right-Click the Armor Stand
