title: Empty test failling
body: <p>I have different span with the <strong>done_by</strong> class and I wanted to know if they are empty or not.</p>
  
  <pre><code>$('.done_by').each(function()
      {           
          var emptyTest = $(this).is(':empty');
          console.log(emptyTest);         
      });
  </code></pre>
  
  <p>And I have only '<strong>false</strong>' responses.</p>
  
  <p>However I have the following code when I inspect my page 
  <img src="https://i.stack.imgur.com/BW5kH.png" alt="enter image description here"></p>
  
  <p>As you can see some are filled and others are empty. But why did I have only <strong>false</strong> responses in my log console ?</p>
  
  <p>I tried with the .length attribute and if else statements but I have the same problem.</p>
