Relates to MC-191096, MC-191698, MC-192498, MC-192791, MC-193404, MC-192956 and MC-192959. Yet another one of the states that depends on other blocks; honestly think they should all be merged into 1, as that's clearly the root cause: states that are set based on neighboring blocks cannot be forced by /setblock anymore.
