level auto increment closing level selection

If you win a level and you start entering and closing the "settings" menu the level will increment +1 for each cycle (allowing player to skip levels as shown in screenshot).
I suppose the bug is in Main.qml file at 83 - 93 lines:
Transition {
    from: "*" // "* ---> won" could solve the problem
    to: "stopped"
    SequentialAnimation {
        ScriptAction { script: {
                if (root.itemsLeft == 0) {
                    root.level++;
                    root.maxLevel = Math.max(root.maxLevel, root.level);
                    //adding "root.itemsLeft--;" is another possible solution
                }
            }
        }
    [...]
}
