IRouteNotifier + NavigationView + MVUX + Navigator not reliable?

[DevTKSS]

Current behavior

Listening to RouteNotifier as described in uno docs from MainModel as corresponding Model to MainPage where the apps NavigationView is placed, the output is case 1 empty string or case 2 "Tab" indicating the TabNavigationBar ib the bottom of this app, but never showing any of the route names in Route registry or xaml named regions.

Expected behavior

If that output would be the current route as expected it would maybe be possible to set the NavigationView Header Content to that Page Title=Route to not havong to add a header definition to each of them

How to reproduce it (as minimally and precisely as possible)

1. Create a app using mvux, regions, DI with recommended template
2. Set app.xaml.cs Route Registry:
   ViewMap s for at least 3 pages incl. Their models, so add one
3. RouteMap:
   Main is nested to shell, second and third page nested to main, second to be default, same as main.
4. Clear each pages current content
5. Add NavigationView to MainPage, incl Region.Attached = true
6. Add at least two menuitems NavigationViewItem s and add Region.Name to each of them to show the correct selection corresponding to shown content
7. On the NavigationView properties place CommandExtensions.Command bound to MainModel to cantral navigation handler
8. If you like to get some "Tab" output, add a TabNavigationBar with named Regions
9. Add some simple content to the second and third page like a textblock with its name
10. Install the IRouteNotifier exactly as told in documentation
11. on route change let it set this text to MainModel IState<string>CurrentHeaderText
12. bind this to the NavigationView.Header

Start and check it out. No header will be there

Anything else we need to know?

Would be nice to be able to set the NavigationView.Header to the current pages header or similar to not have to set this up at each page individually. On wpf or similar pages do have Title property to fill this in, on uno that is at least not available on intellisense...
