vis_flags don't apply to appearances, which is what your object becomes when you add it as an underlay. You'd have to add the object to the vis_contents of the right object, not as an underlay.

In your case, only the vis_flags of the object on the map is respected, since the underlay no longer actually has vis_flags.
