potential memory leak using Q.QPromise

[nenadlazovic]

Hi I am experiencing memory leak in QML app using quickpromise.
I created simple app to demonstrate.
App have timer that does some async operation. async operation is handled using quickpromise.
Code below (with timer 1 sec), leaks approx 1.6MB/min, and eventually crashes (QT 5.11 @ MSWindows or Ubuntu 18)

Any suggestions ?

import QtQuick 2.5
import QtQuick.Window 2.2

import "promise.js" as Q

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World");
    property int syncStoriesTimeoutInSec: 1;

    Component.onCompleted: {
       syncStories();
    }

    Timer {
        id: syncStoriesTimer
        interval: syncStoriesTimeoutInSec * 1000;
        running: false; repeat: false
        onTriggered: {
            syncStories();
        }
    }

    function syncStories() {
        let p = Q.promise(function (resolve, reject) {
            //for test purposes, resolve right away
            resolve({});
        });

        p.then(
            function(data) {
                console.log("resolved");
                syncStoriesTimer.start();
            },
            function(data) {
                console.log("rejected");
            }
        )
    }
}
