Dismissing the Current View from SwiftUI Toolbar takes me to root view - swiftui

Question

I have Three Views: Test1, Test2, Test3. I have a NavigationView on Test1, and a navigation link that takes me to Test2. In Test2, I have a NavigationLink that takes me to Test3, as well as a button that dismisses the current view, and takes me to Test1. In Test3, I just have a button that dismisses the current view, and takes me to Test2. All is well in this scenario.
Here is the complete code:
struct Test1: View {
var body: some View {
NavigationView {
NavigationLink(destination: Test2()) {
Text("Click Me")
}
.navigationBarTitle("Test 1")
}
}
}
struct Test2: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
VStack {
NavigationLink(destination: Test3()) {
Text("Click Me")
}
.navigationBarTitle("Test 2")
Button("Return") {
self.presentationMode.wrappedValue.dismiss()
}
.padding()
}
}
}
struct Test3: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
Button("Return") {
self.presentationMode.wrappedValue.dismiss()
}
.navigationBarTitle("Test 3")
}
}
Now, in Test2, if I move the NavigationLink into a toolbar, so that this is clickable from the Navigation Bar, that is where I am encountering strange behavior. When I click the link in the toolbar to go to Test3, and when I click the Return button in Test3, I am now taken back to Test1, and not Test2 as I would have expected. Here is the revised Test2 code:
struct Test2: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
VStack {
Button("Return") {
self.presentationMode.wrappedValue.dismiss()
}
.padding()
}
.navigationBarTitle("Test 2")
.toolbar {
NavigationLink(destination: Test3()) {
Text("Test 3")
}
}
}
}
How can I have a NavigationLink in Test2, and not be taken back to the root view when dismissed from Test3?
