<p>This tests InsertUnorderedList on a selection that ends at the start of a paragraph.  Since we don't paint the gap before the paragraph for most selections like this, we don't perform InsertUnorderedList on the paragraph that the selection ends in.</p>
<div id="div" contenteditable="true">
This paragraph should be in a list.<br>
This paragraph should not be in a list.</br>
</div>
