To reproduce:

1. Launch the app
2. Push CMD + H
3. The stage will hide but it wont be iconified
4. To check stage state move mouse to the text field which represents 'iconified' state and
wait until the tooltip appears. There you may see all the changes to that property.

Compare observed behavior with the case when you press '-' button.
