I don't use imenu, so I can't really test, but does the following fix
the problem?

diff --git a/lisp/imenu.el b/lisp/imenu.el
index 5084fe61ef..9df597b4d6 100644
--- a/lisp/imenu.el
+++ b/lisp/imenu.el

   (or imenu--index-alist
       (setq imenu--index-alist (list nil)))
-  ;; Add a rescan option to the index.
-  (cons imenu--rescan-item imenu--index-alist))
+  (unless imenu-auto-rescan
+    ;; Add a rescan option to the index.
+    (cons imenu--rescan-item imenu--index-alist)))
 
 (defvar imenu--cleanup-seen nil)
