Hi Po Lu,

Thank you for the prompt fix.

The following test works as expected, i.e., the tab-bar height is
correct at startup:
$ cat .config/emacs/init.el
(tab-bar-mode 1)

However, if a different face is set (either in in early-init.el, init.el
or after Emacs is loaded), the tab-bar height is redisplayed with an
incorrect height. I tried many different approaches and combinations to
enable tab-bar + set a different face, and in all cases the issue could
be reproduced.

See the attached video for a simple demonstration of this new issue.
