In principle, Emacs windows should not be less than `window-min-height'
lines tall.  But an application can temporarily bind that variable to a
smaller value during resizing and leave around a window of less height.
Such windows usually don't harm when maximizing the frame but won't get
us back the previous state when switching back to normal.

On the other hand, switching from maximized to normal and back again
will fail more frequently due to `window-min-height'.  Note also that
the issues I mention here are not reponsible for the bad behavior you
observed earlier.  (Not directly, at least.)
