Ok.

Now I used this:

#+begin_src emacs-lisp
(defun count-markers-in-buffer-undo-list ()
  "Message number of (different) markers in `buffer-undo-list'."
  (interactive)
  (require 'cl-lib)
  (message "%d" (length
                 (cl-delete-duplicates
                  (seq-filter #'markerp (flatten-tree (copy-tree 
buffer-undo-list)))
                  :test #'eq))))
#+end_src

to get the number of different markers in `buffer-undo-list', after
reproducing the recipe.  The answer was always "1".  Just a bunch of
entries referring to one and the same marker.  That seems sane.

Are you able to provide a more pathological recipe?
