I'm getting the error "No operator defined for property header-args" when trying to run `org-property-action` on the `header-args` property below:
* outline header
:PROPERTIES:
:header-args:bash: :tangle yes
:END:
I'm able to set the same properties using
#+PROPERTY: header-args:bash :tangle yes
I've tried running `emacs -Q` and get the same error. I'm using org-version is 9.0.7
