Bug::If item exists, but is not targeted by itemSelector -> plugin fail

[maikelmclauflin]

consider the following code:

<ol class="list-trunk item-container">
    <li class="active">  <!-- item in question -->
        <a class="layer-handle"></a>
        <ol></ol>
    </li>
    <li class="sortable group">
        <a class="layer-handle"></a>
        <ol class="item-container">
            <li class="sortable">
                <a class="layer-handle"></a>
                <ol></ol>
            </li>
            <li class="sortable">
                <a class="layer-handle"></a>
                <ol></ol>
            </li>
        </ol>
    </li>
    <li class="sortable group">
        <a class="layer-handle"></a>
        <ol class="item-container">
            <li class="sortable">
                <a class="layer-handle"></a>
                <ol></ol>
            </li>
            <li class="sortable">
                <a class="layer-handle"></a>
                <ol></ol>
            </li>
        </ol>
    </li>
    <li class="sortable">
        <a class="layer-handle"></a>
        <ol></ol>
    </li>
    <li class="sortable">
        <a class="layer-handle"></a>
        <ol></ol>
    </li>
    <li class="sortable">
        <a class="layer-handle"></a>
        <ol></ol>
    </li>
</ol>

when the sortable plugin is instantiated with the following itemSelector:

handle: '.layer-handle',
itemSelector: '.sortable'

and the first li (with an active class only) is dragged the plugin fails.
I am presuming that this is because the handle cannot find it's item... because it was not selected.

What can be done to remedy this? Is there currently a way to exclude items?

so as i'm going through the code, i'm realizing that it might be more of an issue of the plugin acting on elements that are not items, as defined by the itemSelector
