bug#38111: 27.0.50; globalized-minor-mode not enabled on get-buffer-create

[Juri Linkov]

This looks like a bug.  I found this issue while using global-tab-line-mode,
but to confirm that it's unrelated to tab-line, this bug report uses another
globalized minor-mode global-display-fill-column-indicator-mode:

0. emacs -Q
1. M-x global-display-fill-column-indicator-mode RET
2. C-x b test1 RET
3. RET  ;; this inserts newline to show column indicator
        ;; that confirms this mode is enabled in the buffer

4. M-: (switch-to-buffer (get-buffer-create "test2")) RET
5. RET  ;; no column indicator, mode not enabled
6. C-h v display-fill-column-indicator-mode RET
   ;; confirms its value is nil
