I do think it's a misfeature: Emacs is a bit trigger happy with windows.
When resizing frames/windows, I believe it should generally try to avoid
deleting windows when possible.  Patches in this direction are welcome
(we have already improved this, e.g. by replacing the C-x + code, with
the introduction of adjust-window-trailing-edge, ...).

Between the header-line, the mode-line, and the buffer text itself,
Emacs assumes here that it's more important to show the buffer text.
It may not always be the best choice, but it does make sense.

I'm not sure what better behavior you're thinking of.
