insertElement with partial list selection

[garry.yao]

1. Load sample page with the following content and selection:

   <ul>
   	<li>it[em1</li>
   	<li>item]1</li>
   </ul>
   

2. Open table dialog to insert a default table;

• Actual Result: JavaScript error thrown;
• Expected Result:

  <ul>
  	<li>it<table>...</table>1</li>
  </ul>

Shouldn't the dialog box behave in the same way as insertHtml in API sample?
When HTML is inserted, rest of the second <li> is converted into <li>1</li>
