DesktopHTMLViewer using WebKit renderer - how?

I did remove the new DesktopHtmlViewer and replace it with a HtmlViewer and set the renderer to native. But I have since learned that this is a Windows only issue so on the Mac it really makes little difference… As you suggest…. It did make a little difference though as the old HTML Viewer with native renderer did make the compile app a little smaller but not by much…
