`.PrevInSection` points to a page resource

I’ve got a page bundle that among other things contains a summary.md file as a resource. However, if this is the last page in section, .PrevInSection is not nil and points to summary.md, a page resource, mistaking it for a full-blown page. Is this a feature or a bug?

I’ve worked around it by additionally testing for .Title, which in my case is always empty for this kind of a page resource.
