Usually, you can't make a side window the only window on its frame - the
main window has to stay.  If you ignore window parameters, you have to
clean the state of windows yourself afterwards - for example, by giving
the sole remaining window a 'window-side' parameter of nil.  If you do
not do that, the windows state of the frame is broken already before you
try splitting the window below.

This is a hack and would fail in the case at hand since 'split-window'
would set the 'window-side' parameter for the new window.  I'd rather
set all parameters of the selected window to nil instead.
