[MAC] Shown event won't fire for Dialog when called via the ShowModalAsync call

[VPKSoft]

Hi, I don't seem to get the ShowModalAsync call to fire the Shown event on macOS.

Expected Behavior

A NotImplementedException is thrown.

Actual Behavior

Nothing happens.

Steps to Reproduce the Problem

1. Use the sample code for the dialog.
2. Call the await new TestDialog().ShowModalAsync(this); from another control or form.

Code that Demonstrates the Problem

using Eto.Forms;
namespace amp.EtoForms.Forms
{
    public class TestDialog: Dialog
    {
        public TestDialog()
        {
            Shown += TestDialog_Shown;
        }

        private void TestDialog_Shown(object? sender, EventArgs e)
        {
            throw new NotImplementedException();
        }
    }
}

Specifications

• Version:
• Platform(s): macOS with the Sdk-styled project. I don't know the what it is using: <Project Sdk="Eto.Forms/2.7.0">.
• Operating System(s): macOS Catalina v.10.15.7
• Visual Studio: Visual Studio Community 2022 for Mac Version 17.0.6 (build 4)
• .NET: 6.0.302

This is not urgent in any way - just thought to report the issue.

Ps. Thanks for the great framework 👍🏻 I have started porting my OSS WinForms projects to Eto.

Thanks for reporting the issue! In looking at the code this was certainly an oversight when changing some things around.
