SwiftUI Picker strange behavior when in an EquatableView

I post the minimum code to reproduce the behavior. Tested on latest macOS and Xcode.

The picker in this example is just a wrapper for the default picker and conforms to Equatable (this is a must to prevent the view from updating when properties doesn't change in the real world view) and categories:

enum Category: Int, Identifiable, CaseIterable {
    case one, two, three
    
    var id: Self { self }
    
    var name: String {
        switch self {
        case .one:
            return "First"
        case .two:
            return "Second"
        case .three:
            return "Third"
        }
    }
}

struct CustomPicker: View, Equatable {
    
    static func == (lhs: CustomPicker, rhs: CustomPicker) -> Bool {
        lhs.selectedCategory == rhs.selectedCategory
    }
    
    @Binding var selectedCategory: Category
    
    var body: some View {
        VStack {
            Picker("Picker", selection: $selectedCategory) {
                ForEach(Category.allCases) { category in
                    Text(category.name)
                }
            }
        }
    }
}

And a simple model to bind to:

final class Model: ObservableObject {
    @Published var selectedCategory: Category = .two
}

Now in ContentView:

struct ContentView: View {
    
    @StateObject private var model = Model()
    @State private var selectedCategory: Category = .two
    
    var body: some View {
        VStack {
            Text("Picker bug")
            HStack {
                CustomPicker(selectedCategory: $selectedCategory)
                CustomPicker(selectedCategory: $model.selectedCategory)
            }
        }
        .padding()
    }
}

Here is the problem. If I bind the CustomPicker to the @Stateproperty it works as expected. However, if bound to the model's @Published property the value doesn't change when interacting with the control. When not using the Equatable conformance it works as expected.

What's more interesting is that if I change the pickerStyle to something else like segmented or inline it does work again.

Any idea why this happens? Probably a bug?

EDIT:

I found a hack/workaround... the thing is if the CustomPicker is inside a regular TabView it works fine.

TabView {
    CustomPicker(selectedCategory: $model.selectedCategory)
     .tabItem {
        Text("Hack")
     }
}

Strange behavior...
