[BUG] StatusBarBehavior transparent background when using .net maui shell

Current Behavior

Using the StatusBarBehavior I can successfully set any backgroundcolor on Android and IOS when using the .net maui shell. When I try to set a transparent background, the statusbars background color is white instead of transparent. This happens regardless of setting the Shell.NavBarIsVisible true or false.

Expected Behavior

The background of the status bar should be transparent. This works well when not using .net maui shell (for navigation).

Steps To Reproduce

1. Open the .net maui toolkit sample app
2. Change the StatusBarColor of the behavior to transaprent on the related sample page
3. Disable Shell.NavBarIsVisible on the page
4. Add some demo content inside the scrollview

Workaround for anyone that is interested (I am unsure if this works for AppShell, but works for other type of navigation pattern)

In your MauiProgram.cs you can play around with the WindowManagerFlags for Android:

                 .ConfigureLifecycleEvents(events =>
                 {
#if ANDROID
                     events.AddAndroid(android => android.OnCreate((activity, bundle) => MakeStatusBarTranslucent(activity)));

                     static void MakeStatusBarTranslucent(Android.App.Activity activity)
                     {
                         activity.Window.SetFlags(Android.Views.WindowManagerFlags.TranslucentStatus, Android.Views.WindowManagerFlags.TranslucentStatus);
                     }
#endif
                 })
