Bug with Bug on QML/JS Reformat File? , forEach function is deleted

JRobles

I have the next function:

 onAdditionInfoFetched:{
             //(var info)
            if(!isCurrentStackPage){
                return;
            }
            var msgs = []
            info.forEach(element => {
                             var indexOf = messagesListModel.indexOf("tdid", element.tdid)
                             if (element.type === 0 && indexOf === -1) {
                                 msgs.push(element)
                             }
                         } );
            root.messages = root.messages.concat(msgs)
            root.messagesChanged()
            //listView.positionViewAtEnd()
        }

when I call the Tools > QML/JS > reformat file, the function is changed to this:

 onAdditionInfoFetched: {
            //(var info)
            if (!isCurrentStackPage) {
                return
            }
            var msgs = []
            info.forEach(function element } // <= all the code inside is deleted
            var indexOf = messagesListModel.indexOf("tdid", element.tdid)
            if (element.type === 0 && indexOf === -1) {
                msgs.push(element)
            }
        })
            root.messages = root.messages.concat(msgs)
            root.messagesChanged()
            //listView.positionViewAtEnd()
        }

The inner function on the forEach is removed and is now giving me an error
