This shows that the abesence of a minimization button does not prevent the application from programmatically minimizing the window. KWin and fvwm behave like Windows in this regard, whereas Metacity-based WMs prevent the minimization.
My understanding is that not the absence of minimize/maximize button prevents an ability to programmatically minimize/maximize a window, but an item in the system menu. I'd suggest to also add a test for sending WM_SYSCOMMAND/SC_MINIMIZE/SC_MAXIMIZE behaviour.
