List hierarchy is broken when Display style: Nested Lists and Move second-level items without entries to the end? are both selec

When the "Display style" setting is set to "Nested Lists" and the "Move second-level items without entries to the end?" setting is checked in the module configuration, the output looks like this:

...
<li class="level-0 first">
<a title="" href="/">Resources For</a>
<ul class="container level-1">
<li class="level-1 first"> </li>
<li class="level-1"> </li>
<li class="level-1"> </li>
<a title="Resources for Librarians" href="/librarians">Librarians</a>
<a title="Resources for Researchers" href="/researchers">Researchers</a>
<a title="For Prospective Members" href="/members">Members</a>
</ul>
</li>
...

That is, it outputs the wrapper for the item when it shouldn't and only outputs the link at the end (and not the wrapper).
