DisplayPromptAsync colors the background gray when entering values

[datoml]

Description

If you use the DisplayPromptAsync method to enter values, the background of the page turns gray and remains gray. It is easily reproducible. Simply create a standard MauiApplication and enter the following code in the MainPage.xaml.cs in the OnCounterClicked method.

string result = await DisplayPromptAsync(
    "title",
    "Description",
    accept: "Ok",
    cancel: "Cancel",
    placeholder: "Foo",
    initialValue: "Foo");

After entering some values, the background turns gray and even more gray after closing the dialog.

Steps to Reproduce

1. Create new .NET MAUI Application.
2. Open MainPage.xaml.cs and enter the following code provided below in the OnCounterClicked method.
3. Enter values in the dialog

   string result = await DisplayPromptAsync(
   "title",
   "Description",
   accept: "Ok",
   cancel: "Cancel",
   placeholder: "Foo",
   initialValue: "Foo");

Verified this issue with Visual Studio 17.10.0 preview2 (8.0.7 & 8.0.14). Can repro on android platform

I have the identical issue with Visual Studio 17.9.6 (8.0.61 and prior). Issue appears when using the Android Emulator, but isn't present on an Android local device (Samsung Galaxy S23 Ultra) either in Debug or Deployment. As such, seems like an Emulator issue at least in my case.
