bug#53662: 29.0.50; Cannot use tab-new from side window

[martin rudalics]

Two caveats:

+      (dolist (parameter (window-parameters))
+        (set-window-parameter nil (car parameter) nil))

Maybe you should remove the 'window-side' and the 'window-atom'
parameters only - users can assign arbitrary parameters to windows.

+        (unless (eq tab-bar-new-tab-choice 'window)
+          ;; Create a new window to get rid of old window parameters
+          ;; (e.g. prev/next buffers) of old window.
+          (split-window) (delete-window)))

Note that this will lose other settings as well like the window's
dedicated status.  If this is the intended behavior, you should at least
tell so in the doc-string.
