My tab-bar-tab-name-format-function causes 100% cpu spin as of
ca3763af5c. Disabling tab-bar-auto-width fixes it.
To repro: emacs -Q -l repro.el
repro.el:
(defun aj/tab-bar-tab-name-format (tab i)
(propertize
(propertize " " 'display '(space :width (8)))
'face (funcall tab-bar-tab-face-function tab)))
(setq tab-bar-tab-name-format-function #'aj/tab-bar-tab-name-format)
(tab-bar-mode)
