BindList: complex pages with named lists can cause extra binding

[g105b]

I've found a bug when using named lists.

<ul>
  <li data-list="list-name">Something here</li>
</ul>

Having multiple differently named lists on the same page sometimes causes the list from one bindList call to appear in the wrong list. The solution is always to clamp the context to the containing parent element.

An extra issue I've collected this morning is that using bindList in a component context still requires its component to be passed as the second parameter in order to scope it properly. The ComponentBinder should do this already. I think this is the same bug.

Project: DHPL, user-list.php, binding the pending vs. existing users to two separate lists.
