Ok, I re-implemented the mechanism like bellowing, can you check whether it 
fits?

#+begin_src emacs-lisp
(setq tbl (let ((bound-tags (seq-filter 'cdr fulltable)))
                    (if (length< fulltable org-fast-tag-selection-maximum-tags)
                        fulltable
                      (if (length< bound-tags 
org-fast-tag-selection-maximum-tags)
                          (progn
                            (seq-take (seq-uniq (append bound-tags fulltable))
                                      org-fast-tag-selection-maximum-tags)
                            (message "Tags are limited displayed by 
`org-fast-tag-selection-maximum-tags'."))
                        bound-tags
                        (message "Tags are limited displayed only has key 
bound."))))
              char ?a cnt 0)
#+end_src
