  Issue 1018465: [CSS4-Pseudo] Active selection and hard wrap (or hard return)
  line break: ::selection should not select <br>

  <meta name="assert" content="The &lt;br&gt; element is an empty element. Its background color can be painted but specifying its color should generate no rendering effect of any kind. Since the 'background-color' has been specified as 'transparent', then nothing should be painted or viewable in this test.">

  <style>
  div
    {
      font-size: 100px;
    }

  div::selection
    {
      background-color: transparent;
      color: red;
    }
  </style>

  <script>
  function startTest()
  {
  var targetRange = document.createRange();
  /* We first create an empty range */
  targetRange.selectNodeContents(document.getElementById("test"));
  /* Then we set the range boundaries to the children of div#test */
  window.getSelection().addRange(targetRange);
  /* Finally, we now select such range of content */
  }
  </script>

  <body onload="startTest();">

  <p>Test passes if there is nothing below.

  <div id="test">&nbsp;<br><br><br>&nbsp;</div>
