I have turned my MWE into two almost identical MWE's (attached,
including a diff), so that LaTeX export output shows the problem.
I start with my expectations and then I explain what contains the
LaTeX output for mwe-noweb-ok.org and mwe-links-ok.org.

* LaTeX export objectives

Noweb should work, meaning that the LaTeX output preamble should
contain (above \author) the line:
#+begin_src latex
% Should go to the LaTeX preamble above \author{}.
#+end_src

Resolving links should work, meaning that the LaTeX output should
contain (below \tableofcontents) the line
#+begin_src latex
Listing \ref{noop}, \ref{make-noweb}, and \ref{make-noweb-result}.
#+end_src
where all links have user labels.

* mwe-noweb-ok

Export of mwe-noweb-ok.org to LaTeX shows that noweb works
Noweb works, because the preamble contains:
#+begin_src latex
% Should go to the LaTeX preamble above \author{}.
#+end_src

Resolving the last link fails, because it has an org-id
#+begin_src latex
Listing \ref{noop}, \ref{make-noweb}, and \ref{orgd105392}.
#+end_src
while the caption of the linked listing has a user label.

* mwe-links-ok

Noweb fails, because the LaTeX output preamble does contain
#+begin_src latex
\usepackage{hyperref}
\author{Gerard Vermeulen}
#+end_src
without the LaTeX comment.

Resolving links works, because the LaTeX output contains
#+begin_src latex
Listing \ref{noop}, \ref{make-noweb}, and \ref{make-noweb-result}.
#+end_src

* Problem

I can find no configuration where noweb and resolving the link
to the noweb block works.
