+ // An example of this is when applying chains where the "Undo"
+ // menu state should change when each command executes. But,
+ // since the state changes are ignored, the "Undo" menu item
+ // will never get enabled. And unfortunately, this will cause

+ // state is enabled (even though it isn't) causing the routines
+ // to ignore the new enable request.
+ //
+ // So, the workaround is to transition the item back to disabled
+ // and then to enabled. (Sorry, I couldn't find a better way of
+ // doing it.)
