In my opinion, one way to do it is to have current-window-configuration
store the window-start internally as an integer (instead of a marker),
denoting the position of the display start.

Then, set-window-configuration could set the window-start to that
position.

Would that work? At least that is how I currently work around the issue.

It is! However, the documentation suggests that it is even better, when
it's currently not.

All the best,
