It is actually a glitch (which is fixed in the latest internal builds). The whitespace was significant, and
<a href="#".... >foo</a>
Did not tirgger arrow appearance, while
<li><a href="#".... >foo</a></li>
It turned out to be an inconvenient one, so we fixed it. Anyway, you do not really need buttons inside listview, as it exposes a click event.
