title: requests_html render method continues to result in timeout
body: <p>I'm not sure if it's the setting of my computer (Windows 7, Python3.8, just recently installed requests_html), but no matter which site I choose, the <code>render</code> method is resulting in <code>timeout error</code>
  I have played around with timeout parameter, but no luck.</p>
  <pre><code>import os
  import sys
  import requests_html
  import requests
  import pyppeteer
  
  
  
  def get_request(url, render = False):
  
      session = requests_html.HTMLSession()
      res = session.get(url)
  
      try:
          res.raise_for_status()
      except ValueError as e:
          raise('Dead link')
  
      if render:
          res.html.render(sleep = 2, timeout = 20)
  
      return res, session
  
  
  def test_render():
      url = 'https://www.yahoo.com/'
      res, session = get_request(url, render = True)
  </code></pre>
