Do you see the correct lazy-count values in the minibuffer and comint
after removing `(null isearch-message-function)'?

What do you think about adding `isearch-message' as the default value
of isearch-message-function?  E.g.

#+begin_src diff
-(defvar isearch-message-function nil
+(defvar isearch-message-function #'isearch-message
#+end_src
