    Fix bug #9151 (Wrong reverse search for images and tables).
    
    If the reverse position corresponds to an inset, its paragraph id
    does not follow the main text numbering. Typically, an inset has
    only a few paragraph, so that we would jump near the beginning of
    the document. In this way we at least jump at the beginning of the
    inset.
