[O] [ISSUE] source block coderef link does not work when not under same headline

[stardiviner]

Here is an example, on first coderef link, it can work. But not work on second
same coderef link. Seems because of ~org-link-search~ can't search across 
headline
scope?

#+begin_src org
,* Test coderef in source block

,#+begin_src emacs-lisp
(print "hi")                                                           ; 
(ref:kk)
,#+end_src

[[(kk)]]

,* test across headline

[[(kk)]]
#+end_src
