ContentPage's OnBackButtonPressed not invoked on iOS and MacCatalyst

[MSicc]

Description

The ContentPage's OnBackuButtonPressed method is not invoked on iOS and MacCatalyst.

Seems to work on other Platforms (only tested Android in the simulator).

Steps to Reproduce

1. Create new MauiApp
2. Add a second Page
3. Replace AppShell call with
   MainPage = new NavigationPage(new MainPage());
4. Add a button and add code to navigate to the second Page
   async void NavigateButton_Clicked(System.Object sender, System.EventArgs e) { await this.Navigation.PushAsync(new NewPage1()); }
5. On the second page, override OnBackButtonPressed():
   protected override bool OnBackButtonPressed() { return base.OnBackButtonPressed(); }
6. Set a breakpoint
7. Debug the app, go to the second page, hit the back button - should break in there, but doesn't
