Position of cursor is wrongly computed in a list item inside a document in IE

In the wiki editor, type:

*** test1

*** test2

When editing in wysiwyg mode, the lists html will be

<ul>
<li><br />
      <ul>
      <li><br />
            <ul><li>test1</li></ul>
      </li>
      </ul>
</li>
</ul>

<ul>
<li><br />
      <ul>
      <li><br />
            <ul><li>test2</li></ul>
      </li>
      </ul>
</li>
</ul>

Now, if the caret is positioned in the first list item in the second list, the endOffset reported will be 1, even if it really is before the <br /> (to test this, just type something in, it will be typed before the <br />).

Note that this will not happen for the first list, nor for any of the items on a different level than the first, nor for any other element but the first element in the list.
