I'd like to report a blur situation on the focus of the TextArea. The "focusedProperty" returned by the TextArea is in fact only the focusProperty of the TextInputControl.

If the user grab one scrollBar of the TextArea, the "isFocused" returns false. But IMHO, since the scrollBar is part of the TextArea, and the developer has no API to detect that situation, I would see that the TextArea will still have the focus when the user is playing around with the inner scrollBar.

Because right now, the focus is gone to another object that is not accessible.
