Tangling in code block with a noweb reference breaks polymode

[DeadEarnest]

Tangling when point is outside the code blocks works fine. Also, tangling works fine if there is no <<noweb refs>> inside any code blocks.

This is definitely related to noweb-ref expansion, when a <<ref>> is present but we have :noweb no, tangling works fine.

If you try to run org-babel-tangle when point is in either of the two code blocks, you will get an error message:

unwind-protect: Marker does not point anywhere

:PROPERTIES:
:header-args: :comments no :noweb yes
:END:

#+begin_src clojure :tangle ./test-pm-tangle.cljc
(+ 1 1 1)
<<noweb-ref>>
#+end_src

#+begin_src clojure :noweb-ref noweb-ref
(+ 1 1 1)
#+end_src

After the tangling comes Armageddon:

1. polymode gets disabled
2. font-locking resets to nil
3. current non-hidden org buffer name (without spaces in front of it) vanishes
4. current window scrolls up a bit, leaving point at the bottom of a screen
5. if that's the first time I tangle, a mark is set at current point O_o
