relates to:

• [SR-14800] Missing argument label completion in return value of single expression closure that has return type restricted by protocol #57148

Issue Description:

In the following test case the isActive argument label is not suggested. When removing the x.map closure around it, the argument label is properly completed.

// RUN: %swift-ide-test --code-completion --source-filename %s --code-completion-token=COMPLETE

struct TodayView {
    var x {
        let x = Bool?
        x.map { _ in
            NavigationLink2(destination: true, #^COMPLETE^#isActive: true)
        }
    }
}

public struct NavigationLink2<Label> {
    public init(destination: Label, isActive: Bool) { fatalError() }
}
