popoverTips don't display for toolbar menu buttons in iOS 26.1

[Also submitted as FB20756013]

A popoverTip does not display for toolbar menu buttons in iOS 26.1 (23B5073a). The same code displays tips correctly in iOS 18.6. The issue occurs both in the simulator and on a physical device.

Repro Steps

1. Build and run the Sample Code below on iOS 26.1.
2. Observe that the popoverTip does not display.
3. Repeat on iOS 18.6 to confirm expected behavior.

Expected

popoverTips should appear when attached to a toolbar menu button, as they do in iOS 18.6.

Actual

No tip is displayed on iOS 26.1.

System Info

• macOS 15.7.1 (24G231)
• Xcode 26.1 beta 3 (17B5045g)
• iOS 26.1 (23B5073a)

Sample code

import SwiftUI
import TipKit

struct PopoverTip: Tip {
    var title: Text {
        Text("Menu Tip")
    }

    var message: Text? {
        Text("This tip displays on iOS 18.6, but NOT on iOS 26.1.")
    }
}

struct ContentView: View {
    var tip = PopoverTip()

    var body: some View {
        NavigationStack {
            Text("`popoverTip` doesn't display on iOS 26.1 but does in iOS 18.6")
                .padding()
                .toolbar {
                    ToolbarItem(placement: .topBarTrailing) {
                        Menu {
                            Button("Dismiss", role: .cancel) { }
                            Button("Do Nothing") { }
                        } label: {
                            Label("More", systemImage: "ellipsis")
                        }
                        .popoverTip(tip)
                    }
                }
                .navigationTitle("Popover Tip Issue")
                .navigationBarTitleDisplayMode(.inline)
        }
    }
}
