These articles display properly in Njump, Habla, Coracle, and Nostrudel, but if you check the tags, they refer to an article that is previous/next with "a" tags.

So that a long-form client could add paging through the articles, and 30040 can be auto-created that contains all of the articles in a series, in the correct order, so that they could be displayed in #Alexandria, as a magazine.
