title: Element is not clickable at point in headless mode. But when we remove headless from protractor.conf.js it is working fine.
body: <pre><code>element(by.className('cuppa-dropdown')).element(by.className('dropdown-list')).element(by.className('list-area')).element(by.tagName('li')).click();
  </code></pre>
  
  <p>actually this element is in pop up. ANd it is woring fine in <strong>headless</strong> mode. But as we need to automate the test cases by build in vsts we need to execute test in headless mode</p>
