When a JScrollPane has a row header view, autoscrolling in the
row header is not reflected by the viewport view.

This is demonstrated by the attached code. Compile it and run
it. The left-hand list is the row header view, and the
right-hand list is the viewport view. Click in the right-hand
list and drag down to make the list scroll up. The left-hand
list scrolls with it, so the numbers are still lined up. Now,
click in the left-hand list and drag down to make it scroll up.
The right-hand list does not scroll, so the numbers get out
of alignment.

    for (int i=0;i<200;i++)
    {
      listModel.addElement("" + i);
    }
    
    JList headerList = new JList(listModel);
    headerList.setFixedCellWidth(100);
    JList contentList = new JList(listModel);
    
    JScrollPane scrollPane = new JScrollPane(contentList);
    scrollPane.setRowHeaderView(headerList);
    
    JFrame frame = new JFrame();
    frame.setSize(new java.awt.Dimension(300,300));
    frame.getContentPane().add(scrollPane);
    
    frame.show();
  }

Note this maybe a repeat of 4202002

If I create my own header component and add it to a JScrollPane
it seems that it isn't repainted properly when scrolled. Under
the windows l&f this appears as a grey bar where the component
should be. If I resize the (JInternalFrame) frame then it gets
painted but in the wrong position - the start (x =0) position
of the component is displayed rather than the scroll bar
position. If I now scroll left then I finally see the bar as I
should .
