Bug: weird interplay between enforce dependencies, stuck projects and previous subtree [8.2.10 (8.2.10-23-g1ec416-elpa @ /home/devesh/.emacs.d/elpa/org-20141208/)]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------
When org-enforce-todo-dependencies is t, stuck projects definition is
simply '("+project" ("NEXT") nil ""), and org mode file looks like :

* A                                     :project:
  :PROPERTIES:
  :ORDERED:  t
  :END:
** TODO B
* C                          :project:
** TODO D

Both A and C appear as stuck projects, which is expected behaviour.

But if A itself becomes TODO, like below:

* TODO A                                     :project:
  :PROPERTIES:
  :ORDERED:  t
  :END:
** TODO B
* C                          :project:
** TODO D

Not only A vanishes from stuck projects, but C also vanishes. No stuck
projects are shown for the above file.

One subtree should not affect the next, even if first is ordered and org-enforce-todo-dependencies is t.
