Above works after the below patch:

diff --git a/lisp/ox.el b/lisp/ox.el
index 2be77a87b33..1831432df87 100644
--- a/lisp/ox.el
+++ b/lisp/ox.el

     (org-element-map (org-element-contents scope) 'headline
       (lambda (headline)
  (unless (or (org-element-property :footnote-section-p headline)
-    (not (org-export-numbered-headline-p headline info)))
+    (and (null (plist-get info :with-toc))
+ (not (org-export-numbered-headline-p headline info))))
   (let ((level (org-export-get-relative-level headline info)))
     (and (<= level n) headline))))
       info)))

But I am pretty sure that's not the right way as the default value of
org-export-with-toc is t.
