  Hello,

  Thanks for reporting. Indeed this is an issue that hasn't been fixed
  yet. This is the case for most latex environments

  My solution is here
  https://www.mail-archive.com/emacs-orgmode@gnu.org/msg129974.html

  https://www.mail-archive.com/emacs-orgmode@gnu.org/msg129976.html

  I will try to submit a patch soon.

  Best regards,
  Jeremie
