 Currently the experience for users switching between maps in the !MapMenu
 is non-intuitive.  When they switch from one map to another and then back
 again, they lose their layer state, selection, etc from the first map.
 Numerous users have complained about this defect in our Theme picker.

 It would be extremely useful if the !MapMenu widget could be modified so
 that when a map in the menu is loaded, it modifies the !MapMenu widget on
 the fly to reference the runtime version of itself in the current session
 rather than a map from the library, and so that when re-loading it just
 uses itself rather than creating a new runtime map.
