You said "initially", so I thought you were talking about what
happens before the recipe is started.

Are you saying that you see the echo-area go down to 1 line _after_
the timer is started?  If so, to unlock this puzzle we need to
understand what causes the mini-window to resize back to 1 line.  The
default value of resize-mini-windows is 'grow-only', so it isn't
supposed to shrink back to 1 line.

And nothing else?  I hoped you will see there something that would
explain why the mini-window resized back to 1 line.
