I thought when the two windows are neighbors (which they often enough
are) we could flip them.  But I think the solution is to (1) add for
each live window its number in 'window-state-get' (we need a function
'window-number' for that) and (2) in 'window-state-put', whenever we
split a window, try to find out whether a window with the respective
number is in 'window-dead-windows-table' and reuse it in that case.

It can take longer.  Don't worry.  They'll reply before Emacs 31 gets
out.
