bug#49215: 28.0.50; 'display-time-mode' and 'which-function-mode' not interacting well with 'tab-bar-format-global' |

I've just noticed that somehow in copying the code into my email
below, a "t" was somehow replaced with a "T".
Please accept my apology. Below is the correction.
(setq tab-bar-format
'(tab-bar-format-tabs
tab-bar-separator
tab-bar-format-align-right
tab-bar-format-global))
(tab-bar-mode t)
(display-time-mode t)
(which-function-mode t)
