BUG: 228096


544	544	// only show vertical scrollbar if there are lyrics and is needed
545	545	browser->setVerticalScrollBarPolicy( m_hasLyrics ? Qt::ScrollBarAsNeeded : Qt::ScrollBarAlwaysOff );
546	546
	547	// maybe we were just added, don't have a view yet
	548	if( !containment()->view() )
	549	return;

547	551	const qreal containerOffset = mapToView( containment()->view(), boundingRect() ).topLeft().y();
548	552	const qreal containerHeight = containment()->size().height() - containerOffset;
549	553	const qreal collapsedHeight = ( contentHeight > containerHeight ) ? containerHeight : contentHeight;
