The print preview does not load

[fvanheeswijk]

What happened?

When using the print functionality with the beta runtime the print preview does not load, a loading circle will be shown indefinitely.

Importance

Blocking. My app's basic functions are not working due to this issue.

With the Microsoft Edge Beta application installed the following code should be run in a C# Windows Forms application. Subsequently the Print command should be selected in the context menu after opening the menu by right-clicking on the page.

using System;
using System.Drawing;
using System.Windows.Forms;

using Microsoft.Web.WebView2.WinForms;

namespace WebView2Bug
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Environment.SetEnvironmentVariable("WEBVIEW2_RELEASE_CHANNEL_PREFERENCE", "1");

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(CreateForm());
        }

        private static Form CreateForm()
        {
            var form = new Form
            {
                Size = new Size(1280, 1024)
            };

            var webView2 = new WebView2
            {
                Dock = DockStyle.Fill,
                Source = new Uri("http://example.org/")
            };

            form.Controls.Add(webView2);

            return form;
        }
    }
