Environment

Windows build number: 10.0.20175.0
Windows Terminal version (if applicable): 1.2.2022

Any other software?
N/A

Steps to reproduce

Open Windows Terminal 1.2.2022 from code that supports returning the main window handle; for example in C# .NET

using System;
using System.Diagnostics;
using System.Threading;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            Process p = Process.Start("wt"); // Start Windows Terminal
            Thread.Sleep(1000); // Wait a second to make sure it's open
            Console.WriteLine(p.MainWindowHandle.ToString()); // Print handle to console
            Console.ReadLine(); // Wait for user input before finishing
        }
    }
}

Expected behavior

The handle for the subsequently opened window is returned. In the example above, a numerical value representing the window handle is printed to the console (such as 856282)

Actual behavior

A handle of 0 is returned.
