(Slate) SWindow - SupportsMaximize and SupportsMinimize are both required to be false or the first one won't be respected as false

To reproduce, set SWindow::FArguments::WidgetArgsType::SupportsMaximize to false and try to click on the maximize button (which is now greyed out). Your window should maximize, even though you expect it not to. However, if you also set SupportsMinimize to false, it’ll work.

Nice catch! It looks like that was a typo since it was checking HasMinimizeBox rather than HasMaximizeBox when working out whether to enable that button.
