Bug: org-babel-tangle-comment-links does not honor org-babel-tangle-uncomment-comments in noweb comments [9.1.9 (release_9.1.9-65-g5e4542 @ /usr/local/share/emacs/26.2/lisp/org/)]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

Try the following code;
#+NAME: start
#+BEGIN_SRC emacs-lisp :tangle no
(message "start")
#+END_SRC

#+NAME: end
#+BEGIN_SRC emacs-lisp :tangle no
(message "end")
#+END_SRC

#+BEGIN_SRC emacs-lisp :tangle output.el :comments noweb :noweb yes
start
<<start>>
end
<<end>>
#+END_SRC

#+BEGIN_SRC emacs-lisp :tangle no
(let ((org-babel-tangle-comment-format-beg "start %start-line\n")
      (org-babel-tangle-comment-format-end "end %start-line\n")
      (org-babel-tangle-uncomment-comments t))
  (org-babel-tangle-file (buffer-file-name))
  (with-temp-buffer 
  (insert-file-contents "output.el")
  (buffer-string)))
#+END_SRC

#+RESULTS:
#+begin_example
start 71
start
;; start 285
(message "start")
;; end 285
;; start 1256
(message "start")
;; end 1256
end
;; start 360
(message "end")
;; end 360
;; start 1331
(message "end")
;; end 1331
end 71
#+end_example

You see the noweb comments are commented out. The reason is this cl-wrap
definition in org-babel-expand-noweb-references.

#+BEGIN_SRC emacs-lisp
(let ..
   (c-wrap (lambda (text)
		   (with-temp-buffer
		     (funcall (intern (concat lang "-mode")))
		     (comment-region (point) (progn (insert text) (point)))
		     (org-trim (buffer-string))))))
#+END_SRC
