[Reg 4.8->4.9] QML auto format breaks valid structures

// Imagine we have next var:
readonly property var model: [{
        "delegate": headerLabelComponent,
        "text": qsTr("Display")
    }, {
        "delegate": scaleSliderDelegate
    }, {
        "delegate": switchDelegateComponent,
        "text": qsTr("Dark theme"),
        "value": theme.style === Theme.Dark,
        "checkedCb": function (checked) {
            if (checked) {
                theme.style = Theme.Dark
                return
            }
            theme.style = Theme.Light
        }
    }, {
        "delegate": headerLabelComponent,
        "text": qsTr("Additional")
    }, {
        "delegate": itemDelegateComponent,
        "text": qsTr("emergency call"),
        "onClicked": function () {
            Qt.openUrlExternally('tel:112')
        }
    }]
