If you read the above docstring carefully, you'll see that it doesn't
say "don't make windows smaller than that" but just that if a window
gets smaller it'll be deleted.

I do think it's a misfeature, but it's not one that's trivial to fix.
IIUC Martin has worked on a fix, but he hasn't submitted it yet, so
I guess it's not quite ready for prime time.
