Now I pushed the current patch, together with the new tests
that cover its 'quit-restore' logic in test/lisp/tab-bar-tests.el.
Could you please write a new test that will contain a sequence of
function calls that implement the logic of your configuration.
Then we could see how to improve the window functions
to pass the tests.
I thought Martin agreed that we don't need `(window-dedicated-p window)` in `window-deleteable-p`? That makes my use case work. Or are you waiting for the test case and do you want that stand alone or in the test suite?
