Description

ios: multiple versions
ui-collectionview: 5.3.46 and others (incl 6.0.14)

On iOS I notice that when dragging an item through the list (50 items), the item that is dragged shows up multiple times in the list. When dropped, these duplicates are usually replaced with the actual contents of those items, but sometimes I must scroll through the list to make them change to the correct view.
It seems that the views (reuse) and the data source seem out of sync somehow.

Research direction

No source files, tests, or entry points are named. Reproduce the issue on iOS with a 50-item list while dragging, then inspect the collection view's reuse and data-source behavior; done means the dragged item appears only once and dropped items update without scrolling.
