> Given a spark DataGrid with an ArrayCollection dataProvider, the DataGrid can erroneously go blank in the following situation:
> - the DataGrid has been scrolled down so it is not at the very top.
> - the .source property is changed on the dataProvider to be a new Array where the new values in the Array are also different objects to the objects in the previous .source Array.
> - .refresh() is called on the DataGrid
> This is possibly the same bug as FLEX-33066.
> I will attach a minimal test case.
