title: dropdown with selected item, how to get its name/ label using capybara
body: <p>Given the following dropdown:</p>
  
  <pre><code>&lt;select id="my-dropdown" name="my-dropdown"&gt;
    &lt;option value="1"&gt;Peter&lt;/option&gt;
    &lt;option value="2" selected&gt;Pan&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I know I can get the value (2 here) of the current selection using this code:</p>
  
  <pre><code>find_field("#my-dropdown").value
  </code></pre>
  
  <p>But how can I get the name/ label (Pan here) of the current selection? The following code does <strong>not</strong> work:</p>
  
  <pre><code>find_field("#my-dropdown").label
  </code></pre>
  
  <p>Thanks :)</p>
