MessageBox not closing in PowerShell

First time user. I have a simple class created to display a Message box.

public class Msg : IDisposable
    {
        public Msg(string Message)
        {
            Application.Init();
            var msg = MessageBox.Query(20, 10, "Test", Message, "Yes", "No");
        }

        public void Dispose()
        {
            Console.Write("\u001b[?1h");
        }
    }

When I use the class from within PowerShell, the MessageBox opens but does not disappear once a option is chosen. What am I missing?

Since this is a gui.cs<->Powershell issue/discussion…

I spiked a possible powershell integration for gui.cs at https://github.com/wgross/gui.ps1. I did this out of curiosity and don’t have a real-world application currently to drive further implementation but maybe it can serve as a stimulus or starting point for other people?

I still don’t understand how that gap in mouse functionality still persists in the new Windows Terminal.

Me either: I guess they are working on it. This is tracked here: https://github.com/migueldeicaza/gui.cs/issues/332
