Window.Parent is null with Classic Navigation

[dansiegel]

Description

When not using Shell & recursing up Element.Parent this currently will stop at the Window as the Window.Parent is null rather than being set to the Application. This prevent any custom code at runtime to recurse the UI tree and access the Application. This appears to be a problem when NOT using Shell.

Shell Stack	Classic Stack

SAMPLE
MauiApp2.zip

Steps to Reproduce

1. Create MAUI app
2. Do not use Shell
3. Once everything has been parented... such as OnAppearing recurse the Parent until null... the Window.Parent will be null

Setting the Main Page to a Shell Works correctly

public partial class App : Application
{
    public App()
    {
        InitializeComponent();
        MainPage = new AppShell();
    }
}

Setting the Main Page to a Page does not...

public partial class App : Application
{
    public App()
    {
        InitializeComponent();
        MainPage = new MainPage();
    }
}

It makes no difference if setting the MainPage property or overriding CreateWindow
