Thanks, @tsayao 

I'm running these tests now on Linux (Ubuntu 20.04) and MacOS (13.3.1):

- controls:test
- Manual/ StartIconified
- System/Robot test.robot.javafx.stage.IconifyTest
- System/Robot test.robot.javafx.scene.SceneChangeShouldNotFocusStageTest

On Linux, all of them work fine.
On MacOS:
 - Work fine
 - I see the stage, it is not iconified (with or without your patch). Is this a know issue?
 - Works fine
 - Fails: it is not iconified (with or without your patch, also I had another issue with scene being null). Is it a known issue as well?
