If I replace the line
(with-selected-window (window-normalize-window window t)
of 'window-max-chars-per-line' by the line
(with-current-buffer (window-buffer window)
the problem persists. So it is not the 'select-window' call per se
that causes the trouble. The problem is with having that separate
frame that gets its echo area resized. I'm not sure what causes it
but I suppose it's 'window-configuration-change-hook' itself that
selects that frame for running the hook.
Using 'window-size-change-functions' (patch attached) instead of
'window-configuration-change-hook' fixes the problem here.
