> The precedence rules written into the spec are very problematic and it would be a bear to implement them. For example, if you attempt to maximize an iconified stage on Windows it will de-iconify. Making it stay iconified and maximize later would take real effort. Maximizing an iconified stage on Mac does nothing (glass loses the maximized state) and fixing that would also take a lot of work. I really think our time would be better spent leaving things as-is and updating the spec.

I agree we should do an update on the documentation and accept that platforms differ on some aspects (that are acceptable) such as this one.

Maximize maybe there's the case to start maximized to cover the screen for single-application use machines (common in enterprise software). I don't see the use for iconify.

I have removed this test and the related ones that test state precedence order.
