You didn't say how to evaluate that; there's more than one way.  If I
evaluate with "M-x eval-region RET", the mini-window doesn't grow; if
I evaluate with "C-x C-e" or C-j after the closing parenthesis, it
does grow.

So it sounds like one doesn't need such a complex recipe, the
different behavior is visible already on the first evaluation.
