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.

This likely is a duplicate of MCPE-28890 if I've understood it properly.
I don’t think this is a duplicate of MCPE-28890 because that ticket is about random update order in a horizontal hopper pipe. This ticket is just about a hopper that is being pulled from still being able to push when it has more than one item in it. This is working as intended per MC-6162. See also MCPE-35159 on hoppers pushing and pulling at the same time.
@AlexanderJ.: this report is already resolved "Working As Intended." That means we have determined that the behavior is not a bug.
In your test world, the reason some blocks go in the top chest is because the top hopper sometimes collects 2 blocks before the hopper under it pulls one out. That was explained in the comments above by Umija5895M.
If you simply add another hopper to the top of your column and have it point into a block or empty space, then all of the items will go to the bottom chest.
Items will be "pulled" by lower hoppers one-at-a-time. However, if the top hopper contains more than one item, as in the case of having a water column, it can also push items out of its own pipe. So you will get items in both the top and bottom chests. Changing this is essentially a feature request.
