OnBeforePopup return false but new windows open [a target="_blank"]?

[gap032]

HI,
i've implemented cefsharp 1.25.0 with WPF (it must support .NET3.5), handle filedownloads and opening external links with IE like below:

bool ILifeSpanHandler.OnBeforePopup(CefSharp.IWebBrowser browser, string url, ref int x, ref int y, ref int width, ref int height)
{
            if (url.Contains(home_url))
            {
                  return false;
            }else{
                Process.Start("IExplore.exe", url);
                return true;
            }
}

bool IRequestHandler.GetDownloadHandler(IWebBrowser browser, string mimeType, string fileName, long contentLength, ref IDownloadHandler handler)
        {
            handler = new DownloadHandler(fileName);
            return true;
        }

in DownloadHandler(string fileName) with savefiledialog i've got messagebox:

...
Application.Current.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(() =>
                {
                    MessageBoxResult result = MessageBox.Show(Application.Current.MainWindow, msg, "Message1", MessageBoxButton.YesNo, MessageBoxImage.Question);
                    if (result == MessageBoxResult.No)
                    {
                        _templocation = true;
                    }
                }));
...

to handle downloading file to temp location. When download link has target="_self" attribute everything works ok, but when it has target="_blank" a new blank window apperars on top of messagebox.

How can I close from code that new blank window or force to now show it?

OK, I found workaround:
#198

As I read the CEF API doc for OnBeforePopup() you should return true (not false) if you wan't to suppress the popup.

Anyway since you found another workaround and this sounds more like a question than a bug I will close this issue. I hope that's OK 😄
