QQuickWindow::afterSynchronizing() called before Animator has started when using QQuickView and QWidget::createWindowContainer()

    Description

      The following example displays a BusyIndicator while expensive QML is loaded. It does so by waiting until the afterSynchronization() signal of QQuickWindow is emitted before it begins the loading. However, the signal is emitted before the indicator's animator has begun, causing it not to spin until the QML has loaded.

      With the patch below applied, the application will print out this output:

      qml: after sync

    BusyIndicator {
//        running: loader.status === Loader.Null

      A workaround is to use a short timer to delay loading.

      The equivalent widget-less Qt Quick application works:

      main.qml
      import QtQuick 2.0
import QtQuick.Window 2.0
import QtQuick.Controls 2.0

Window {
    id: window
    width: 400
    height: 400
    visible: true

    Connections {
        target: window
        onAfterSynchronizing: {
            print("after sync");
            loader.active = true
        }
    }

//    Timer {
//        running: true
//        interval: 50
//        onTriggered: {
//            print("setting loader.active to true")
//            loader.active = true
//        }
//    }

    Loader {
        id: loader
        active: false
        sourceComponent: Column {
            anchors.fill: parent

            Repeater {
                model: 20000
                delegate: Button {
                    text: index
                }
            }
        }
    }

    BusyIndicator {
//        running: loader.status === Loader.Null
        anchors.centerIn: parent
    }
}

      It prints out this output:

      I ran both applications with QSG_RENDER_LOOP=threaded.
