title: How to select the closest element with a specific tag in chai protractor
body: <p>If the html looks as follow:</p>
  
  <pre><code>&lt;form&gt;
     &lt;div&gt;
        &lt;field-component&gt;
           &lt;div class='field'&gt;&lt;/div&gt;
        &lt;/field-component&gt;
     &lt;/div&gt;
     &lt;div&gt;
        &lt;div class='icon'&gt;&lt;/div&gt;
     &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I am able to get the field using <code>fieldElement = element(by.css('.field'))</code>, but how can I get the closest element with the <code>icon</code> class?</p>
