Comment 9 for bug 1417291

Looking at the mockup at http://openstack-homepage.bitballoon.com/docs/book, it seems that TOC lists are in a div with class "docs-sidebar-toc". If this is true, rather than deleting the above Javascript line, a better solution might be amending it as follows:

    $('div.docs-sidebar-toc ol > li:has(ul)').addClass('docs-has-sub');
