EditButton stops working just by adding the package (retroactive Binding Equatable)

Hi, thanks for the package!

I ran into a SwiftUI issue where EditButton stops toggling edit mode simply by adding this package, even if I don’t use any of its views.

Minimal repro:

var body: some Scene {
    WindowGroup {
        NavigationStack {
            NavigationLink(destination: {
                List {
                    Text("Row")
                }
                .toolbar {
                    EditButton()
                }
            }, label: {
                Text("Push")
            })
        }
    }
}

When the package is included, EditButton doesn’t change the edit state anymore (no visible effect).
If I remove the package, it works as expected.

I tracked it down to this code:

extension Binding: @retroactive Equatable where Value: Equatable {
    public static func == (lhs: Binding<Value>, rhs: Binding<Value>) -> Bool {
        lhs.wrappedValue == rhs.wrappedValue
    }
}

Even in a project without this package, adding the above extension alone reproduces the same issue (EditButton state no longer toggles).

This retroactive conformance seems to affect SwiftUI’s internal diffing/state updates.

Would you consider removing this global conformance or scoping it to a custom wrapper type instead?

Thanks!

@mrsunx Fascinating! Good find. Thanks so much for looking into this. I can't remember now why I added that extension, but I will definitely see about removing this.
