    Web: Handle description lists with extra stuff in the accessibility tree
    
    Description lists can have their term+value items inside divs, e.g.
    for styling. When that occurs, the browsers seem to be pruning the
    extra divs from the accessibility tree (i.e. making them just a simple
    description list from our perspective). However, if the author does
    something to force inclusion of those divs (e.g. making them focusable
    via the tabindex attribute), we'll no longer have the clean accessibility
    tree we had before.
    
    This commit handles description lists with expected stuff in their
    accessibility tree, and should also prevent us from accidentally
    including terms from a nested description list in the term count of
    its parent description list.
    
    See issue #248
