That's strange since if the frame is 22 pixel higher there should be
more space.  Please tell me the values of `delta' and the one returned
by the `window-max-delta' call when the failure happens.

What gives (window-pixel-height (frame-root-window)) in both cases?  And
maybe also (window-pixel-height (selected-window)) and that of the other
live window?
