title: QtWebegnine jstProcess is not defined
body: <p>I'm trying to open a simple html file (something like this)</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;h1&gt;hello&lt;/h1&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>which does not have any embedded or external JavaScript, inside QtWebEngine using this code</p>
  
  <pre><code>import sys
  
  from PyQt5.QtCore import QUrl
  from PyQt5.QtWidgets import QApplication
  from PyQt5.QtWebEngineWidgets import QWebEngineView
  
  class Browser(QWebEngineView):
      def __init__(self):
          self.view = QWebEngineView.__init__(self)
          self.setWindowTitle("Loading ...")
          self.titleChanged.connect(self.adjustTitle)
  
      def adjustTitle(self):
          self.setWindowTitle(self.title())
  
  if __name__ == "__main__":
      app = QApplication(sys.argv)
      view = Browser()
      view.showMaximized()
      url = QUrl.fromLocalFile("simple.html")
      view.setUrl(url)
      sys.exit(app.exec_())
  </code></pre>
  
  <p>But when i run it the following error appears in the console</p>
  
  <pre><code>js: Uncaught ReferenceError: jstProcess is not defined
  </code></pre>
  
  <p>What is jstProcess and how can i define it? (The code works fine if I load some remote resource like bing.com) </p>
