It goes back to normal in the echo area but leaves the minibuffer window
alone as you say.

I had assumed "go normal" meant "shrink back to normal size", which is true for the echo area but not the minibuffer.

Can you tell me more about this inconsistency?

Well, first, to clarify, I was talking about unpatched Emacs, and using window-size-change-functions in an attempt to catch window size changes.

1. window at 80x24, mini-window at 1 line, window thinks it's 80x24. Everything okay.

2. mini-window grows to 2 lines

3. window at 80x23, mini-window at 2 lines, window thinks it's 80x24. Inconsistent, but temporary.

4. user resizes window to 79x23. size-change-functions called.

5. window at 79x23, mini-window at 2 lines, window thinks it's 79x23. Everything okay again.

6. mini-window shrinks.

7. window at 79x24, mini-window at 1 line, window thinks it's 79x23. Permanent inconsistency.

Am I missing something here?
