Hello, I have a problem with Ext.grid.Panel when dragging columns that are off screen.
Suppose there is grid with multiple columns and some columns are accessible only when you scroll to them. So scroll to the rightmost column and try to drag it. Once you click column header, drag wont start but scrollbar jumps immediately to start and column that you try to drag is hidden off screen again.See fiddle

Any workaround would be welcome.
