But, there's still one small detail as keen-eyed readers may have noticed. In Safari, when dismissing the full preview, it animates back into the preview view and springs back to the original position. With our implementation, however, it doesn't. The preview view controller does animate back into the preview view, however, instead of returning to the original position, it disappears off into the middle of the screen. This is because there's still one `UIContextMenuInteractionDelegate` method we need to implement: `contextMenuInteraction(_:previewForDismissingMenuWithConfiguration:)`. Similar to the `previewForHighlighting` method, this method takes the interaction and the context menu configuration, creating a `UITargetedPreview` that should be used during the dismissal animation. Since we want the preview to go back to the same location while dismissing as it came from while expanding, we can cache the targeted preview we've already constructed for the highlight method and return it from the dismissal method.
