commit 29458ec7d2843baa725f9b613d0e935df3a61301

    * lisp/tab-bar.el (tab-bar-select-tab): Set window-state-put WINDOW arg to 
nil
    
    WINDOW arg nil will always create a new window regardless of the value
    returned by 'frame-root-window' that is nondeterministic - it returns
    an internal window when there are more than 1 window on the frame/tab,
    otherwise it returns a live window that was reused between different tabs
    (bug#46904)
    (tab-prefix-map): Bind "u" to 'tab-undo'.
