NSItemProvider loadObject in SwiftUI Drag and Drop

Question

I am dragging and dropping views using a DropDelegate in SwiftUI. I'm successfully wrapping my data in an NSItemProvider using the .onDrag View Modifier, and I even have .onDrop working if I am able to have my drop data be one of the stored properties of my DropDelegate.

I'm trying to allow for decoding my drop data using the provided DropInfo. I update my view in the dropEntered(info:) delegate method, so that the user can have a preview of their drop before it occurs. When I write

info.itemProviders.first?.loadObject(...) { reading, error in
...
}

The completion handler is not called. If I were to instead write this closure in the performDrop(info:) delegate method, the completion handler would be called. Why is the completion handler only called in performDrop(info:)? Is there a way to have drag & drop previews while performing the necessary changes in real time while not having the data model changed in dropEntered(info:)?

I don't love that I edit my data model in dropEntered(info:), and I haven't gotten to how it would work if the user were to cancel the drag and drop somehow... Perhaps there's a better way to go about this that will allow me to edit my data model in performDrop(info:)?

Thank you!

Edit

Here's the code to reproduce the bug:

struct ReorderableForEach<Content: View, Item: Identifiable>: View {
    let items: [Item]
    let content: (Item) -> Content
    
    var body: some View {
        ForEach(items) { item in
            content(item)
                .onDrag {
                    return NSItemProvider(object: "\(item.id)" as NSString)
                }
                .onDrop(
                    of: [.text],
                    delegate: DragRelocateDelegate()
                )
        }
    }
}

struct DragRelocateDelegate: DropDelegate {
    func dropEntered(info: DropInfo) {
        let _ = info.itemProviders(for: [.text]).first?.loadObject(ofClass: String.self) { item, error in
            print("dropEntered: \(item)") // Won't trigger this
        }
    }
    
    func performDrop(info: DropInfo) -> Bool {
        let _ = info.itemProviders(for: [.text]).first?.loadObject(ofClass: String.self) { item, error in
            print("performDrop: \(item)") // Will trigger this
        }
        
        return true
    }
}
