If I run this block I get test as a result, but all its properties have been stripped.

#+BEGIN_SRC emacs-lisp :results drawer
(propertize "test" 'font-lock-face '(:foreground "red") 'help-echo "tooltip")
#+END_SRC

#+RESULTS:
:RESULTS:
test
:END:

Does anyone know where this happens and if it can be avoided?

Thanks,
John
