Crafters cannot receive redstone power from one block above them as shown in the attached image, causing inconsistency with droppers and dispensers.

To reproduce:

• Place a dropper with a block on top, followed by a redstone block.
• Put an item in the dropper.
• Remove the block between the dropper and the redstone block.
• Repeat the test with a crafter instead of a dropper.

Observed results:

• The dropper spits out the item when the block is broken and the neighbour update is given, while the crafter stays unpowered.

Expected results:

• Both the dropper and the crafter spit out their items.
