In section 2 of "Working with UI Controls" the instructions state to add `@Environment(\.editMode) var mode` to the `ProfileHost` view and use that binding to show either the profile summary or the profile editor:if self.mode?.value == .inactive {
ProfileSummary(profile: profile)
} else {
Text("Profile Editor")
}When previewing the canvas in live mode it seems the `mode` variable is always nil and thus it never shows the profile editor. Tapping the edit button seems to have no effect.
