TextInput.cursorRectangle isn't updated when the text property changes but not the cursorPosition

import QtQuick 2.0


Rectangle {
    id: root
    width: 480; height: 480

    MouseArea {
        id: mouseArea
        anchors.fill: parent
        hoverEnabled: true
    }

    Rectangle {
        anchors.fill: textInput
        anchors.margins: -10
        color: "lightsteelblue"
    }

    TextInput {
        id: textInput
        anchors.centerIn: parent
        width: 300

        text: mouseArea.pressed ? "WWWW" : "aaaa"
        focus: true

        cursorDelegate: Rectangle {
            color: "yellow"
