Listview does not group years to newspaper | ephemera consistenty.

Description

We encountered a strange behaviour in single collection view (listview plugin) with newspaper and ephemera.

• In case of newspaper the main title (anchor of the newspaper) is listed and the years are shown as subelements.
• In case of ephemera all issues are shown as toplevel items, the anchor element is shown as last toplevel item.

After some research, I think it is working with newspaper only by mistake as the issues do not have the corresponding collection ("Newspaper"). In case of the example with ephemera, all levels (anchor, year, issue) have the same collections.

Questions, I can't answer:

• Is it right, that all issues have toplevel:true in their Solr record?

Expected Behavior

The years should be shown below the anchors (newspaper or ephemera) and the issues should not be shown at all.

Affected Versions

This appears in Kitodo.Presentation 2.x and 3.x (master).
