Cancelling the Drag of a Home Screen Icon May Not Leave Icons in their Previous Location

As of iOS 11, Home Screen icons are managed using a new "Drag" option accessed through the VoiceOver Actions menu. If you start performing a drag, and then use the "Cancel Drag" option from the Actions Menu, you will commonly find that the item initially marked for dragging ends up in a different location on the Home Screen to where it was at the start.
