Items not always removed #2
Description
The drag and drop demo was very useful, thanks!
In DragDropDemo, I found that if I was quick enough doing the drag and drop, the item was sometimes not removed, as below. I initially discovered this in my own app where the two listviews were closer to each other and the issue happened frequently. I think it has something to do with testing the HitTest result in TodoItemList_DragLeave, but I'm not sure as this is new to me!
