Theme bug of listview & collapsible.

[vrbvillor]

<ul data-role="listview" data-inset="true" data-shadow="false" data-theme="b">
    <li data-role="collapsible" data-iconpos="right" data-inset="false">
        <h2>HTML / CSS</h2>
        <ul data-role="listview" data-theme="a">
            <li><a href="http://www.runoob.com/html/html-tutorial.html">HTML</a></li>
            <li><a href="http://www.runoob.com/html/html5-intro.html">HTML5</a></li>
            <li><a href="http://www.runoob.com/css/css-tutorial.html">CSS</a></li>
            <li><a href="http://www.runoob.com/css3/css3-tutorial.html">CSS3</a></li>
            <li><a href="http://www.runoob.com/bootstrap/bootstrap-tutorial.html">Bootstrap</a></li>
            <li><a href="http://www.runoob.com/foundation/foundation-tutorial.html">Foundation</a></li>
        </ul>
    </li>
</ul>

The sub-listview appears theme b not a.

The first collapsible topic contains one item without data-theme="a", so it remains theme b.

@apsdehal What's your code for? The outlook of yours is not what I want.

Yeah, I know, I found another bug in the process which needs to be fixed and will fix this one in result.
