 <p>This tests for a bug where InsertLineBreak would insert a '\n' instead of a &lt;br&gt; if the caret was set just before an input field. You should see two input fields each in its own paragraph below.</p>
 <div id="div" contenteditable="true"><input type="text"><input type="text"></div>

 <script>
 div = document.getElementById("div");
 window.getSelection().setPosition(div, 1);
 document.execCommand("InsertLineBreak");
 </script>
