title: QWebView not loading external CSS
body: <p>I am using a QWebView to display some content and I want to use custom CSS to spruce up the output.  I found that I can use the <code>QWebSettings.setUserStyleSheetUrl()</code> method to load my own CSS into the view.  The <code>.css</code> file is in the same directory as my main program.</p>
  
  <pre><code>self.webview = QWebView(MainWindow)
  self.webview.settings().setUserStyleSheetUrl(QUrl.fromLocalFile("myCustom.css"))
  </code></pre>
  
  <p>However, the custom stylings don't load when I add the content to the page using <code>setHtml()</code>.  I have tested that the CSS is properly applying to the HTML in a standard browser.</p>
  
  <p>Any idea what I am doing wrong?</p>
