Thanks for the request.  I tested winner-mode, and noticed many problems:
some intermediate micro-steps saved, etc.  So I implemented a different solution
for tab-bar-history-mode.  And pushed to master, because this is not a 
regression:
it worked this way in Emacs 27, but the fix might break some workflows in Emacs 
28,
so we need more time to test the new solution in master.
