Inconsistency: Some wooden items don't burn in furnaces

Some minor inconsistencies/oversights in what burns in a furnace and what doesn't.

Boats, Doors, Wooden buttons, Signs, Ladders, Food bowls, Bows and Fishing rods. None of these things burn, even though there often are closely-related items that do.

None of the above items will burn in a furnace, even though things like note blocks, wooden pressure plates, trapdoors, crafting benches and even chests and trapped chests will.
