Here is a simple test:

,#+NAME: hello1
,#+BEGIN_SRC sh :var name=""
  echo "hello, $name"
,#+END_SRC

,#+BEGIN_SRC sh :noweb yes
<<hello1(name="chris")>>
,#+END_SRC

,#+NAME: hello2
,#+BEGIN_SRC emacs-lisp :var name="" :results output
(prin1 name)
,#+END_SRC

,#+BEGIN_SRC emacs-lisp :noweb yes :results output
<<hello2(name="chris")>>
,#+END_SRC

,#+BEGIN_SRC emacs-lisp :results output
(prin1 "hi")
,#+END_SRC

,#+RESULTS:
: "hi"

#+end_src

#+begin_src emacs-lisp :results output

       (org-element-context) ; <----- REASON!! cause `match-string-no-properties' result wrong.
