title: Error when declaring an HtmlPage using HTMLUnit
body: <p>When I use this code:</p>
  
  <pre><code>try (final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45)) {
              webClient.getOptions().setJavaScriptEnabled(true);
              final HtmlPage page = webClient.getPage("http://www.chemicalformula.org/calculators/chemical-formula-calculator");}
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>SEVERE: runtimeError: message=[An invalid or illegal selector was specified (selector: '*,:x' error: Invalid selector: :x).] sourceName=[http://www.chemicalformula.org/sites/all/themes/chemical_formula_2/jquery.js] line=[4] lineSource=[null] lineOffset=[0]
  </code></pre>
  
  <p>I've seen threads with people saying it's AngularJS, but the thing is that I cannot edit the code on that website, so I can't fix it by changing the website code.</p>
  
  <p>I have tried using other browser versions, but they all return the same error.
  Any help?</p>
