.NET Maui安卓平板应用：按电源键恢复时如何无空白跳转至根页面？

我正在为安卓平板开发一款.NET Maui应用，需求是按下电源键后，回到应用时需显示根/主页面。

App.xaml.cs代码 #

public partial class App : Application
{
    public App()
    {
        InitializeComponent();

        MainPage = new NavigationPage(new InitialPage());
    }

    protected override Window CreateWindow(IActivationState activationState)
    {
        Window window = base.CreateWindow(activationState);

        window.Stopped += Window_Stopped;
        window.Resumed += Window_Resumed;

        return window;
    }

    private void Window_Resumed(object sender, EventArgs e)
    {

    }

    private void Window_Stopped(object sender, EventArgs e)
    {
        MainPage.Navigation.PopToRootAsync();
        //Inspecting the navstack shows that the PopToRoot worked
        //but on the device the screen got blank
    }
}

截图情况 #

PopToRootAsync执行前

PopToRootAsync执行后

问题现象 #

在Window_Stopped方法中执行PopToRootAsync后，导航栈检查显示PopToRoot操作已生效，但再次按下电源键恢复应用时，设备屏幕会变成空白。
