[MC-80230] Furnace fuel handles invalid item count incorrect

Relates to:

MC-80096

Can be caused by:

MC-79820

Apparently since 1.8.4 you cannot use negative *Count* values (or also 0) for items anymore to create infinite dispensers, droppers... (see MC-80055). I guess this is intended. If so this report is valid.

This seems to affect nearly every block which can reduce the item count:

Dropper
Dispenser
Hopper
BrewingStand (simply don't work)
Using the item
Furnace ⚠️

However the fuel slot of furnaces seems to be the only left out way to decrease the count. Putting an item with count 0 in it, will decrease it infinitely.

How to reproduce:

Use

/summon ArmorStand ~ ~ ~ {Equipment:[{id:stick,Count:0}]}

Right click the ArmorStand
Place the stick in the furnace (do not right click with the stick)

Why sould mojang fix something that appears when using an invalid count?

Because like I said you can get this invalid count for example by using MC-79820. And apprently they fixed this bug for all the other blocks like Dropper, Dispenser... (like I said). Only the fuel slot of the furnace still causes this problem

Seems to be fixed in 15w42a and probably earlier. When the player tries to interact with an item with an invalid count now, the game just removes the item.
