Overflow Menu click disabling Immersive mode - Android 4.4 Kitkat

Question

Anybody know if this is a Bug or is supposed to do this. When clicking the Overflow icon while using KitKat's Immersive mode, it disables the immersive mode. Anybody else running into this?

Full Code by Google - Here

public void toggleHideyBar() {

    // The UI options currently enabled are represented by a bitfield.
    // getSystemUiVisibility() gives us that bitfield.
    int uiOptions = getActivity().getWindow().getDecorView().getSystemUiVisibility();
    int newUiOptions = uiOptions;
    boolean isImmersiveModeEnabled =
            ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);
    if (isImmersiveModeEnabled) {
        Log.i(TAG, "Turning immersive mode mode off. ");
    } else {
        Log.i(TAG, "Turning immersive mode mode on.");
    }

    // Navigation bar hiding:  Backwards compatible to ICS.
    if (Build.VERSION.SDK_INT >= 14) {
        newUiOptions ^= View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
    }

    // Status bar hiding: Backwards compatible to Jellybean
    if (Build.VERSION.SDK_INT >= 16) {
        newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;
    }

    // Immersive mode: Backward compatible to KitKat.
    // Note that this flag doesn't do anything by itself, it only augments the behavior
    // of HIDE_NAVIGATION and FLAG_FULLSCREEN.  For the purposes of this sample
    // all three flags are being toggled together.
    // Note that there are two immersive mode UI flags, one of which is referred to as "sticky".
    // Sticky immersive mode differs in that it makes the navigation and status bars
    // semi-transparent, and the UI flag does not get cleared when the user interacts with
    // the screen.
    if (Build.VERSION.SDK_INT >= 18) {
        newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
    }

    getActivity().getWindow().getDecorView().setSystemUiVisibility(newUiOptions);
}

Something that worked well for me - hopefully this will help those who come back to this in the future.

You can use a Handler to change the flags after the overflow menu appears. On my devices, the back button still appears but the black navigation bar is not visible (Disappears before it appears visibly).

// Creates the PopupMenu.
PopupMenu popup = new PopupMenu(getContext(), view)
{
    @Override
    public void show()
    {
        // Shows the menu.
        super.show();

        // Sets the UI flags to prevent weird changing of window.
        Handler temp = new Handler();
        temp.postDelayed(new Runnable()
        {
            @Override
            public void run()
            {
                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);
            }
        }, 50);
    }
}
