title: Python requests_html render runs forever on certain URLs
body: <p>I am trying to write a simple script that given an arbitrary URL will return the title tag of that website. Because many of the URLs I want to resolve need to have JavaScript enabled, I need to use something like requests_html's render function to do this. However, I have encountered an issue with the library where the example URL below never terminates. I have tried the timeout arg of the render call and it did not work. Can anyone help me figure out how to get this to timeout properly or some other work around to make sure it doesn't get stuck? </p>
  
  <p>This is my current code that does not terminate (it gets stuck on the render call):</p>
  
  <pre><code>from requests_html import HTMLSession
  
  session = HTMLSession()
  r = session.get('http://shan-shui-inf.lingdong.works/')
  # render with JS
  r.html.render(sleep = 1, keep_page=True)
  # Also does not work: r.html.render(sleep = 1, keep_page=True, timeout = 3)
  
  
  title = r.html.find('title', first=True).full_text
  </code></pre>
  
  <p>I have already tried solutions like: <a href="https://stackoverflow.com/questions/492519/timeout-on-a-function-call">Timeout on a function call</a> and <a href="https://stackoverflow.com/questions/35490555/python-timeout-decorator">Python timeout decorator</a> which still did not timeout strangely enough. </p>
  
  <p>NOTE: I am using Python 3.7.4 64-bit on Windows 10. </p>
