Display OSM candidate matches to multiple wikidata item together in candidate matches

[brierjon]

When a duplicate Wikidata item is matched it would be useful to display them in a group to compare. and resolve either through a merge or other action.

OSM candidate matches multiple Wikidata items [show on map]

Having both coordinate markers on the map is useful, but the display group would allow less jumping between listings.
