[O] Bug: Figure caption highlighting [8.3.6 (8.3.6-7-g4d7d52-elpaplus @ /home/mcg/.emacs.d/elpa/org-plus-contrib-20161017/)]

[mcg]

I am not sure if this qualifies as a bug:
When I use figure captions in org-mode I get:

#+CAPTION: Caption text is highlighted
#+CAPTION[Figure with short caption for LaTeX TOC export]: Caption text 
is not highlighted

I know that the short-caption brackets are probably only intended for
LaTeX export. Is there an easy fix to get code highlighting for figures 
with short captions?.
