Made a bridge of acacia planks in my world and then made a map. Stairs do display, but the planks themselves do not, instead a dark gray color.
Recreate problem:
Build anything will acacia planks, then create a map of the area
Expected behavior:
Acacia colored build will show on map
Actual behavior:
Dark gray build shows on map instead
