      Description

        This is an assert that was added recently as part of 6948538.
        It seems to occur more readily with iCMS, much less readily with CMS.
        It is likely that it's just that the new assertion checking is
        uncovering an existing bug that was not uncovered prior to
        the additional assertion checking.
