Dear org community, I have also faced the problem and have made a patch to fix it. This patch would not be the best solution since I'm unfamiliar with Emacs Lisp and the detailed implementation of org-mode. I'd appreciate that if you would review and merge the patch attached to this mail.
Kind regards, Mamoru
