[Koha] ISBD view of multiple publishers

Hi, whenever a biblio has two or more entries in 260$a (place of publication) and/or 260$b (name of publisher), the ISBD view lists them grouping places first, and then names, regardless of the order in the MARCxml, e.g.: Roma : Mosca : Editori Riuniti ; MIR, 2003. rather than: Roma : Editori Riuniti ; Mosca : MIR, 2003. from the MARCxml: 260 _aRoma : _bEditori Riuniti ; _aMosca : _bMIR, _c2003. This applies to both OPAC and librarian's interface. Koha's Bugzilla lists that as a bug, along with several others, which might have been solved, meanwhile. Is there any known workaround? Many thanks, Giuseppe.
