        Test for <i><a href="https://bugs.webkit.org/show_bug.cgi?id=29431">bug 29431</a>
        [Qt] REGRESSION:(r50665) QWebFrame::setScrollBarPolicy(Qt::Vertical,Qt::ScrollBarAlwaysOff) has no effect.
    </p>
    <p> This test ensures the correctness of two scrollbar behaviour:</p>
    <ul>
        <li> This tests that after setting 'overflow' on the document element to
            'hidden' and back to 'visible', scrollbars appear as necessary.
        </li>
        <li>
            After explicitly setting a scrollbar policy different than 'auto', WebCore
            honors that until it is unset.
        </li>
    </ul>
