I found a bug, i can clone items whit Hopper

Put the summary of the bug you're having here

What I expected to happen was...:
one drop items on the hopper(WIP)

What actually happened was...:
item despawen and the hopper forward to a chest.

Steps to Reproduce:
1. Press q and a item is dropt, but don't dispawen on edge of the hopper
2. a hopper forward this item to the chest, but a item don't dispawen.
3. a item dispawen in any time from a map, a hopper stop a forwarding to a chest.

when you have a line of hopper (copling to next hopper) you can drop one item of any hopper, but a item dispawn when you drop a next item on a underlying hopper.
The item on a last (underlying) hopper don't dispawen and is a prio 1 for clone bug.

Sorry 4 me bad english.
