I disagree with this not being a bug. (Obviously, since I submitted it) A bug is when something isn't working as intended. Having the hopper attach to the side of the furnace to specifically feed the fuel slot shows that the hopper is intended to streamline the smelting process. Since the continued processing within the furnace is hindered by the empty bucket, I would say that it is interfering with the intended functionality of the hopper and could be considered a bug. I'll consider this to not be a bug when the Resolution is set to Works As Intended.
