Making a double copper chest with waxed and non-waxed allows a double and defaults to non-wax

To reproduce:

Place a waxed copper chest next to a non-waxed copper chest (which would make a double copper chest)

If you pick block both sides (or break 1 chest and pick block the other), it will default to a non-waxed chest

Expected:

Either prevent a double chest or save the block state when destroying a 1 of the chests in a double chest
