A DESCRIPTION OF THE PROBLEM :
I'm developing a x-platform desktop app with a resizable main window primaryStage.setResizable(true), after I have clicked the little green button to go into full screen mode and then back again to normal mode the resizing of the window is no longer possible. It works on Windows and Linux but not on MacOS.

I have a question out on StackOverflow regarding this issue and was told this i most likely a bug introduced from jdk-9.

REGRESSION. Last worked in version 8u152

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Make a JavaFX application, set primaryStage.setResizable(true)
2. Run application
3. Click the little green maximize button on window to enter full-screen mode
4. Click the little green button again to resume to normal screen mode
5. Resizable window is no longer resizable

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Window should continue to be resizable after coming back from full-screen mode.
ACTUAL -
