Sculk sensors detect vibrations inconsistently with blocks that take up more than one block of space. Opening and closing a chest will emit vibrations from both parts of the chest, but:

• Placing and breaking a bed won't emit vibrations from the farther side of the bed
• Opening and closing shulker boxes won't emit vibrations from the upper shell of the box.
• Extending and retracting pistons won't emit vibrations from the head of the piston.
• Doors won't emit vibrations where they're not opened or powered.

Expected is that the other double blocks behave like large chests, or the large chests behave like other double blocks.
