The wiki states that placing a container above the hopper doesn't check for floating items to collect. However, this is not the case as when you throw items inside the composter, it is still collected by the hopper below it, despite the composter being defined as a container.
Steps to Reproduce:

1. Recreate the setup as shown by setup.png, by placing a hopper, then a composter directly above it
2. Throw an item inside the composter

Observed Results:
The item entity is sucked up by the hopper.
Expected Results:
The item should not get sucked up by the hopper, since the composter is considered as a container. The behavior is expected to be similar to the chest as shown in expected.png, where the item entity is still floating even though it is still within the collection range of the hopper.
