[Message part 1 (text/plain, inline)]

Thanks for checking out the patch.  Try this:

(defun my/tab-bar-tab-name-format-function (tab i)
  (propertize
   (tab-bar-tab-name-format-default tab i)
   'mouse-face '(:inverse-video t))) ; or a named face
(setopt tab-bar-tab-name-format-function
#'my/tab-bar-tab-name-format-function)

And move the mouse over the tab. It should invert. It does for me.
