[clarin-dspace-v9-testing]: Search result list structure changed – different DSO types use different containers

[AmadHashmi]

In v7, all search results (communities, collections, items) were rendered inside a ds-clarin-item-box-view with a .card wrapper.
In v9, only items use .card / ds-clarin-item-box-view; communities and collections are rendered via ds-listable-object-component-loader with [data-test=list-object].
