1. Enable tab-bar-mode and then alter tab-bar-format to show groups. Something like this:
(setq tab-bar-format '(tab-bar-format-history tab-bar-format-tabs-groups tab-bar-separator tab-bar-format-add-tab))
2. Create three tabs: A, B, C. Now switch to A and use M-x tab-bar-change-tab-group and name it "foo". Now switch to C and name it "foo" also.
3. The tab bar groups are _not_ merged; with a large array of tab bars, this causes endless confusion as there are man duplicae tab groups. You would expect a tab group to coalesce like tab group members into a singular tab group --- that is after all their purpose.
This fixes it as I sort the entries before changing the frame parameter.
(defun tab-bar-tabs-set (tabs &optional frame)
"Set a list of TABS on the FRAME."
(set-frame-parameter frame 'tabs (seq-sort-by (lambda (el) (alist-get 'group el nil))
#'string-lessp
tabs)))

Thanks for the bug report. We had a discussion about this problem
in the past, and in the result we arrived at such a solution that the
customizable variable `tab-bar-tab-post-change-group-functions' provides
an option `tab-bar-move-tab-to-group', so that when you select it,
then after changing the group name the tab is moved to its tab group.

I did not check if that solves it, but this issue -- and how I discovered it -- manifests itself when you use `display-buffer-in-[new]-tab' and set a tab group that way.
This can result in a large amount of distinct tab group entries for the same tab group; does `tab-bar-tab-post-change-group-functions' also resolve this?
Because just about anybody who'd use said display buffer action would find themselves in this predicament and that variable (and subsequently adding that function to it) is... unintuitive.

Your guess is right. After customizing this variable and using e.g.
(add-to-list 'display-buffer-alist
'("buffer1" .
(display-buffer-in-tab
(tab-name . "C")
(tab-group . "foo"))))
it merges the new tab with its group.

So you suggest to make this value the default? Ok, the default value
will be changed in the release branch.

Good stuff. Thanks, Juri.

I feel it's what people expect to happen -- what do you think?

I was unsure about this, but now that you raised this question, I agree
it would be natural for people to expect their groups don't get
scattered over the whole tab bar. So now this is changed in emacs-29.
Thanks for suggesting this before the next release, so we had a chance
not to postpone this improvement for another release cycle.
