Run the application below. As it comes up, the TextArea is adorned with scroll bars, as it should be. As soon as you start typing, the scroll bars disappear - this should not happen. They come back when they are "needed", that is, when the text exceeds the visible space. Looks like "ALWAYS" is interpreted as "AS_NEEDED".
