This is fixed in the most recent stable version of Org, i.e. 8.3.3¹ ,
which, I guess, will be part of if Emacs 25.2 or 26.1 (whichever comes
first and allow new features).  It’s also fixed in 8.2.10².  I guess
Emacs-25 should switch v8.2.10.  [Honestly, when v8.3 couldn’t be merged I
did not cross my mind to upgrade to v8.2.10].  In case v8.2.10 it too
radical, a "local fix" must be applied to the version of Org in emacs.git.

Thanks,
Rasmus
