Affects both wooden and iron doors. I was unable to recreate this with similar objects like trap doors, fence gates, etc.

Steps to reproduce:

• Place a door and place redstone in front of the door.
• Change the redstone dust to dot.

• Place a redstone torch above the redstone dust on the door and switch the redstone dust to cross.

Expected result: After the redstone is unpowered, the door will close.

Actual Result: The door stays open even though the redstone is unpowered.
