title: Box Shadow on table row not appearing on certain browsers
body: <p>CSS box-shadow on table rows - <code>tr</code> - doesn't seem to be working consistently across browsers. On some browsers the shadow is displayed; on others, there is no shadow.</p>
  
  <p>I'm using the following CSS:</p>
  
  <pre><code>tr {
    background-color: rgb(165, 182, 229);
    box-shadow: 0px 2px 2px black;
    -moz-box-shadow: 0px 2px 2px black;
    -webkit-box-shadow: 0px 2px 2px black;
  }
  td, th {
    padding: 5px;
    text-align: left;
  }
  </code></pre>
  
  <p>Here is a <a href="http://jsfiddle.net/FYt6X/1/" rel="noreferrer">jsFiddle</a> of the below snippet:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="true">
  <div class="snippet-code snippet-currently-hidden">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>tr {
    background-color: rgb(165, 182, 229);
    box-shadow: 0px 2px 2px black;
    -moz-box-shadow: 0px 2px 2px black, ;
    -webkit-box-shadow: 0px 2px 2px black;
  }
  td, th {
    padding: 5px;
    text-align: left;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;table&gt;
    &lt;tr&gt;
      &lt;td&gt;&amp;nbsp;&lt;/td&gt;
      &lt;th&gt;One&lt;/th&gt;
      &lt;th&gt;Two&lt;/th&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;th&gt;Title&lt;/th&gt;
      &lt;td&gt;Three&lt;/td&gt;
      &lt;td&gt;Four&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;th&gt;Title2&lt;/th&gt;
      &lt;td&gt;Five&lt;/td&gt;
      &lt;td&gt;Six&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;th&gt;Title3&lt;/th&gt;
      &lt;td&gt;Seven&lt;/td&gt;
      &lt;td&gt;Eight&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;th&gt;Title4&lt;/th&gt;
      &lt;td&gt;Nine&lt;/td&gt;
      &lt;td&gt;Ten&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p><strong>Note:</strong> The same behavior is observed when substituting <code>&lt;tr&gt;</code> with <code>&lt;div&gt;</code> and adding <code>display: table-row</code>.</p>
