When maximized, the constraints where applied anyways, causing the window to still be maximized but not show as maximized. The change is to not apply constraints when not floating (meaning floating on the screen - not maximized, fullscreen or iconified).

I've tested a bit more on linux mint (not a KDE desktop), see no ill effects.

There were a couple of warnings opening modal and regular windows, but the same warnings are present in the master branch.

For completeness sake, here they are:

Color picker -> custom color -> use?
`(java:64981): Gtk-CRITICAL **: 15:36:07.237: gtk_window_resize: assertion 'width > 0' failed`


tools -> FxTextArea Embedded in JFXPanel
`(java:64981): Gdk-WARNING **: 15:37:06.136: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.`
