Reloading data does not restore task position

In the example attached, we have our basic demo Gantt with React and Typescript, where we have a button to reload the data into the Gantt, which is working correctly.

The wrong behavior (as you'll see in the video) is that when we change siblings' positions, even when we reload the data, the position is not being reset. If we change the parent or level (or any other data), the data reloading resets everything correctly.

For performance reasons, the React Gantt has the syncDataOnLoad config set to true by default, which will update the dataset and not replace it, if you set up that config to false it will replace correctly

project: {
            eventStore: {
                syncDataOnLoad : false,
            }
        }
