[O] [BUG] ORG-LIST-END-MARKER when exporting from within a babel block with an exclude or include tag

[Frozenlock]

Ok, I know this a very specific application. Perhaps it's not even a
bug and I'm using it the wrong way.

Here is a minimum working example:
----------------------------------------------------

#+TITLE: Test org file
#+EXPORT_INCLUDE_TAGS: test2

* First heading                                                       :test1:
Testing, 1-2, 1-2.

* Second heading                                                      :test2:
Because we can.

** Now a list
   - First item
   - Second item

#+BEGIN_SRC emacs-lisp :results raw :exports results :var
buffer-file-name=(buffer-file-name)
(let ((org-export-babel-evaluate nil)); don't evaluate in 'recursive' exports
   (org-export-as-ascii org-export-headline-levels))
#+END_SRC

----------------------------------------------------

If you export this file to PDF (C-c C-e d), babel will evaluate and
export the file as ascii. However, the ascii file will have the
undesirable "ORG-LIST-END-MARKER" in it.
Here is the resulting ascii export:

----------------------------------------------------

Any idea on how to fix this?
