Detecting when system buttons are visible while using 'immersive mode'

Question

I'm currently using immersive mode (API 19) for one of my Activities as follows:

getWindow().getDecorView()
            .setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                            | View.INVISIBLE);

This hides the system buttons and notification bar until the user swipes for them back. This works fine, however I wish to detect when the user makes the buttons visible again. I've tried a OnSystemUiVisibilityChangeListener but it does not trigger for this particular event.

Any ideas?

From Android Developers video, when you're in immersive sticky mode, the app isn't notified.

Immersive sticky mode starts at 6:56 and around 7:25 Roman Nurik tells that the listener won't be triggered.
