in my case internet explorer will open an url with serverside rending , this will changed the title from about_blank to his own title and recreate the complete DOM.
So i can close tab once, but these will nothing changed.
Now is my dirty solution
Close WIndow -> useWindow->browser.Element.GetTopLevelWindow this close the correct whole Window
Someone an idea?
I’ve tried already invoke com method, attach window.
below some Screenshot if they can help
