HtmlUnit css not applied properly
<p>I try to save the google page using HtmlUnit. But I can't get proper UI. When I check the saved page codes style tags are empty.</p>

<p>My code is here.</p>

<pre><code>public static void main(String[] args) throws IOException {

    FileUtils.cleanDirectory(new File("/home/user1/Documents/Aaa")); 
    WebClient webClient = new WebClient(BrowserVersion.CHROME);
    webClient.getOptions().setCssEnabled(true);
    webClient.getOptions().setJavaScriptEnabled(true);
    webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.waitForBackgroundJavaScriptStartingBefore(1000);
    webClient.waitForBackgroundJavaScript(1000);
    webClient.getOptions().setTimeout(5000);
    System.out.println("******************loaded**********************************");
    try {
        HtmlPage page = webClient.getPage("https://www.google.com");
        page.save(new File("/home/user1/Documents/Aaa/index.html"));
    } catch (Exception e) {
        System.out.println("******************catch***********************************");
        e.printStackTrace();
    }
    webClient.close();
    System.out.println("******************finished********************************");
}
</code></pre>

<p>And my page looks like</p>

<p><a href="https://i.stack.imgur.com/344VO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/344VO.png" alt="enter image description here"></a></p>

</code></pre>

<p>Any idea for this case?</p>

<p><strong>Edited</strong>:
   I think that error is parsing when the CSS3 filter property. In the google page code like this.</p>

<pre><code>filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#4387fd,endColorstr=#4683ea,GradientType=1)
</code></pre>

<p>In this filter has a colon and progrid has a colon. So this leads to CSS Parsing error. Any solution for this?</p>
