_build option list=local doesn't return .PrevInSection or .NextInSection for children

I am not sure if this is intended or not, but I have a section in which I set the _build option to list=local and render=false (_index.md). Basically I don’t need an extra page for this section, but it helps to structure my content.

I can range all pages of that section without a problem. However, when I am inside one of the child pages, the variables .PrevInSection and .NextInSection do not return anything. Is this intended? If I remove list=local the variables return other pages.

Is there another way to kind of hide a section page but keep .PrevInSection etc?
