"var" and "variant" type properties emit valueChanged signal even when value remains unchanged

import QtQuick.Controls.Basic

ApplicationWindow {
    id: root
    width: 640
    height: 480
    visible: true

    property int intVal: swt.checked ? 100 : 100
    property var varVal: swt.checked ? 100 : 100

    onIntValChanged: console.log("intValChanged:", root.intVal)
    onVarValChanged: console.log("varValChanged:", root.varVal)

    Switch { id: swt }
}
