Hello all,

I created a VM, installed Emacs 26.2 fresh, and installed various versions
of org-mode using the tar.gz files from https://orgmode.org/

I replaced org-mode in /usr/share/emacs/26.2/lisp/org with various older
versions until I found the version of org-mode that breaks the helm tags
completion.

I found that the latest version of org where the feature works is Org-mode
version 9.1.9.

I will spelunk around in the code to see what might have changed the
behavior - if anyone has
suggestions or doesn't have this problem with an older version of org,
please let me know - it could
easily be something that I have set incorrectly.

Thanks,
--Nate
