ContentPage Property InputTransparent = true, causes blank page

[xrysanwlh]

Description

When setting ContentPage property InputTransparent to true, the page appears blank.

Is that the expected behavior?

Migrating from Xamarin Forms and InputTransparent property seems to have change behavior. What changed?

Steps to Reproduce

1. Create a new .NET MAUI app
2. Add a button which sets content page's InputTransparent property to true, when clicked:

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
    }

    private void OnButtonClicked(object sender, EventArgs e)
    {
        this.InputTransparent = true;
    }
}

3. The page turns blank, and all the elements disappeared
