Can't set focus with tab key when text fields are in a form (iPadOS)

I don't know if this is a bug but when you put text fiels in a form, pressing the Tab key on a physical keyboard will just jump to the first field and stay there:

import SwiftUI

struct ContentView: View {
    enum FocusedField {
        case firstName, lastName
    }
    
    @State var name = ""
    @State var lastName = ""
    
    @FocusState private var focusedField: FocusedField?
    
    var body: some View {
        Form {
            TextField("Name", text: $name)
                .focused($focusedField, equals: .firstName)
            TextField("Last", text: $lastName)
                .focused($focusedField, equals: .lastName)
        }
        .padding()
        .onAppear {
            focusedField = .firstName
        }
    }
}

This is the result:

Note that this works fine on macOS or when using the Tab key on the virtual keyboard.

If you put the fields into a VStack instead, you'll be able to move through the fields via the Tab key.
