Shortcut item mis-alignment

I'm trying to remember how I triggered this. I think I:

1. Went to "edit shortuct" and clicked to choose a different set.
2. Created a new set.
3. When I went to add a new shortcut, it looked all stupid.

Here's the (prettified) generated HTML:

<div class="toolbar-drawer clearfix">
    <div class="toolbar-shortcuts">
      <ul class="menu">
        <li class="first leaf"><a href="/core/node/add">Add content</a></li>
        <li class="leaf"><a href="/core/admin/content">Find content</a></li>
        <li class="leaf"><a href="/core/admin/dashboard">Dashboard</a></li>
        <li class="last expanded active-trail"><a class="active-trail" href="/core/admin">Administer</a>
          <ul class="menu">
            <li class="first last leaf active-trail"><a class="active-trail active" href="/core/admin/config/modules">Configuration and modules</a></li>
          </ul>
       </li>
    </ul>
  </div>
  <a id="toolbar-customize" href="/core/admin/config/system/shortcut/shortcut-set-2">edit shortcuts</a>
</div>

I was testing #609100: Should not be able to re-add same shortcut to same set twice at the time, though even with that rolled back I still see it. Can anyone else reproduce this?
