Can you please give a more detailed scenario of what happens in
practice.  Is this prevalence of pixel sizes something which occurs
after the frameset was restored or already during restoration?

It shouldn't harm to do that.

We probably should add code to reset all frame parameters installed by
`frameset--record-relationships' after the frameset has been restored.

BTW I've never been able to understand why we don't have code to
remove frame and window parameters.  'frameset--' parameters are just
gruft for the following session IIUC.
