Generated lists for Tables and Figures are not being published to HTML5

This is what happens if I add headlines to the generated list of figures, tables, authors what ever:

I can include the lists in the FrameMaker toc, but when published as HTML5...

I will get a blank page. There is some code / lack of code, that means FrameMaker can't figure out how to handle these documents.

Well... I have had a chat with an Adobe employee who would look into it. We shall see what happens 🙂

yeah well... TOC and Index are really buillt into the HTML5 "product". Like this:

The index words can acessed directly in the HTML5. And I would somehow expect that similar generated lists  like  a list of figures would be automatically integrated. But I can not make that work for what ever reasons.

Not at present, but I have tried adding headings like the rest of the book. But what happens is, that I get the headings in the HTML5 navigation, but the content is a 404 page. I would believe that generated lists are no different from a toc or an index and it should not be necessary to include them via headings. But even if that was NOT the case and headings were the proper way to go, HTML5 publishing still ought to work. Adding cross references won't work either.
