I can't get any proper documentation output on 4.06.1. This happens even after pinning to dune master, which has an issue which seemed to be similar to what I'm seeing.

Steps to reproduce:

1. Install 4.06.1 and dune/jbuilder.
2. Clone https://github.com/rizo/order.
3. Run jbuilder build @doc.
4. Open _build/default/_doc/_html/index.html
5. Click on the order package.
6. Click on the Order module.
7. Click on the Ordered interface. You should get a 404 -- this resource wasn't created.

Running on odoc itself produces similar issues -- nothing is created inside the odoc package.

(To try out pinning to dune master, you currently have to use dune as the package name and prompt opam to create it, or both dune and jbuilder will not be available.)
