The datapreview map used by ckanext geoview does not work after changing ckanext.spatial.common_map.type either to custom or to another map.type

There is an issue where there config for ckanext-geoview preview dataset map interferes with the mapwidget on setting ckanext.spatial.common_map.type configuration in the ckan.ini. Is it possible to set the default map as OpenStreet maps (https://tile.openstreetmap.org/{z}/{x}/{y}.png) for both the maps. This issue started after the removal of Stamen terrain tiles as the default map

Start by tracing the ckanext-geoview preview dataset map and the mapwidget configuration referenced in the issue, using ckan.ini settings for ckanext.spatial.common_map.type as the reproduction setup. Verify how changing that setting affects both maps and define done as consistent default OpenStreetMap tiles without breaking custom or other map types.
