Partially filled hoppers can delete bonemeal from composters

The Bug

Hoppers can delete bonemeal from a composter on top if each slot of the hopper has a single item (That isn't bonemeal and is not a full stack). It would be expected that the hopper would leave the bonemeal in the composter and not delete it, as if all slots of the hopper are completely filled with full stacks.

When the hopper checks if it can take the bonemeal item from the compostor

1. Checks if all slots are 100% fill
2. If fill, stop
3. If not fill, removes bonemeal from the compostor and tries to insert it into the hopper
4. If it can insert the bonemeal, it does so and stops
5. If it can't insert
   →  Return bonemeal to the compostor
   →  Stop
   The hopper should just not take the bonemeal before testing if it can actually fit

To reproduce

1. Fill a hopper by placing one item in each slot (That isn't bonemeal and is not a full stack
   
2. Place a composter on top
3. Fill the composter up
   → At the last level, the hopper will grab the bonemeal from the composter, but because each slot has an item and the hopper is not filled with full stacks, the item will be deleted
