as of today's (20190118) org-plus-contrib, this seems fixed. Quick
check :
===================================================================
# Noweb syntax check
#+property: header-args:python :session
#+property: header-args:sage :session
#+name: A
#+begin_src sage
L.append(i)
#+end_src
#+name: B
#+begin_src sage :noweb yes :exports both
L=[]
for i in range(1,6):
<<A>>
L
#+end_src
#+name: C
#+begin_src python
L.append(i)
#+end_src
#+name: D
#+begin_src python :noweb yes :exports both
L=[]
for i in range(1,6):
<<C>>
L
#+end_src
===================================================================
Thanks a lot !
