Bug? Two `.alert` modifiers mean only last one works?

ContentView.Swift

//
//  ContentView.swift
//  TestAlert
//

import SwiftUI

struct ContentView: View {
	@State private var showAlert1: Bool = false
	@State private var showAlert2: Bool = false
	
    var body: some View {
		VStack {
			Spacer()
			Text("Hello, World!")
			Button(action: { self.showAlert1 = true}, label: { Text("show Alert 1")})
			Button(action: { self.showAlert2 = true}, label: { Text("show Alert 2")})
			Spacer()
		}
		.alert(isPresented: self.$showAlert1, content: {
			Alert(title: Text("Alert 1!"))
		})
		.alert(isPresented: self.$showAlert2, content: {
			Alert(title: Text("Alert 2!"))
		})
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
