In the [C-c C-q] org-set-tags-command, I found it does not complete tags in current buffer.

#+begin_src emacs-lisp
(defun org-set-tags-command (&optional arg)
  ...
  (let* (...
         (local-table (or org-current-tag-alist (org-get-buffer-tags)))
         ;; the `org-current-tag-alist' is from my customized `org-tag-persistent-alist'.
         ...)))
#+end_src

Steps to reproduce:

1. create an empty Org mode file and open it as a Emacs buffer.
2. Fill in Org content as bellowing

#+begin_src org
* headline 1  :tag1:workflow:

* headline 2 :tag2:name:
#+end_src

3. save buffer
4. Press [C-c C-q] org-set-tag-command
5. You can't see buffer local tags "tag1", "tag2", "workflow", "name" in tags completion.
