StackLayout doesn't handle Repeaters with async loading

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Loader {
        asynchronous: true
        sourceComponent: StackLayout {
            id: sl
            currentIndex: 0
            anchors.fill: parent

            Repeater {
                model: 10
                Text {
                    text: `${index}: ${StackLayout.index} - ${sl.currentIndex}`
                    color: "black"

                    Component.onCompleted: console.log("created", index)
                }
