      The bug

      Redstone wire in some situations uses different logic for connecting visually (in which direction the dust texture goes) and logically (what gets powered).

      Glowstone should possibly not show redstone wire on its side since all other blocks which only transfer a redstone signal upwards have no wire on their side.
