    delete from mdds in reverse order (tdf#139820)
    
    This is a more elegant solution from Noel, compared to my previous
    commit. Deleting in reverse order means the underlying std::vector
    used by mdds does not have possible to-be-deleted items to move
    around that forward order would have.
