title: grunt build giving different output
body: <p>I have empty cells in the table (<code>&lt;td&gt;&lt;/td&gt;</code>). The CSS property of empty cells is</p>
  
  <pre><code>table tr td:empty {
      width: 25px;
  }
  </code></pre>
  
  <p>For the table --</p>
  
  <pre><code>&lt;table style="empty-cells:show;"&gt;&lt;!-- rows and columns --&gt;&lt;/table&gt;
  </code></pre>
  
  <p>This code is working fine but after I do a grunt build, the property for empty cells is not getting loaded although it is in the minified CSS.
  Any possible reason for this or any solution to it?</p>
