With Info history or with Isearch history?

Here is how to restore the window position
when navigating back in Isearch history:

#+begin_src emacs-lisp
(setq isearch-push-state-function
      (lambda ()
        ;; Recenter new search hits outside of window boundaries
        (when (and isearch-success
                   (not (pos-visible-in-window-p)))
	  (recenter))
        `(lambda (cmd)
           (when isearch-success
             (set-window-start nil ,(window-start))))))
#+end_src
