Stacked hoppers behave strangely illogical

Stacked hoppers behave strangely illogical in item elevators with water. See the example world, start the circuit (lamp off) and observe the result.

the top and bottom chests contain items.

It would be logical:

• All items end up in the top chest, until this is full
• All items end up in the lowest chest. (Equal to the Java version)
• The count of items is halved with each chest down.
