`dune build @doc` does not rebuild pages

Expected Behavior

I have modified some mli interface and I expect to see the changes after running dune build @doc.

Actual Behavior

After running dune build @doc, I see nothing (the command exit code is $0$). Worst than that, if I undo my modifications (the git staged area is clear), the index pages is produced, but the link to individual modules' documentation are dangling pointers. The first time I ran dune build @doc they were not. I also tried dune build @doc --force, but it has no effect.

I use dune cache. I have tried to deactivate it (using --cache=disabled CLI option), but it does not change anything.

I also tried to remove the _build directory but the problem still occur.

Reproduction

I am not sure how to reproduce this.

Specifications

• Version of dune (output of dune --version): 3.7.0
• Version of ocaml (output of ocamlc --version): The OCaml toplevel, version 4.14.1
• Operating system (distribution and version): Linux Debian Bullseye

Start by reproducing the issue with dune build @doc using the reported Dune 3.7.0 and OCaml 4.14.1 setup, then compare behavior with and without dune cache and with --force or --cache=disabled. Done means modifying an .mli causes the documentation pages to rebuild and leaves valid links to individual module documentation.
