                Please look at the frame 'WordWrappingTest'
                It contains two TextAreas that have text 'This text should be wrapped.'
                One of them has a vertical scrollbar only. Another has no
                scrollbars at all.
                If their text is not wrapped at word boundaries and you partially see
                mentioned text, the test failed.
