Possibly bug in createSnapshotOfSelectedRows()


I have a ListBox with multiple selection and vertical scrolling enabled,
I can reorder items by dragging them from one position up or down to another. However, when I have multiple selections, and one or more of these selected items is visible because of scrolling, createSnapshotOfSelectedRows() fails to create the proper Image.

Worse, if only a fraction of a selected item is shown in the ListBox,
the Drag&Drop Image also contains that fraction, even with just a single selected item - very ugly!

Now before hacking Jules wonderful code, perhaps someone already knows how to fix this?
