Describe the bug

When a barrel is emptied by a hopper, instead of being empty, it will contain an Air block. This Air block keeps the barrel from accepting any more items.

You need to right-click the barrel to "pick up" the Air block, at which point the barrel starts accepting items again. This is not functional on automated setups where the barrel is fed by a hopper.

To Reproduce
Steps to reproduce the behavior:

Make the following setup :

H1
B
H2

With H1 being a hopper filled with compostables, and H2 being an empty hopper.

First the barrel will fill, then start composting. When it is finished composting, H2 extracts the dirt block from the barrel, but the barrel doesn't start filling up again with compostables. Hwyla will show it filled with an air block.

Now right-click the barrel to pick up the air block, and the barrel starts filling up again.

Expected behavior

When the barrel is emptied it should just accept more items.

Screenshots

(here the hopper is filled with compostables so the barrel should be filling up)
