Undo and Redo doesn’t work on zoom functionalities.

Hello,
The Undo functionality doesn’t watch the Zoom settings. The dev team didn’t intend it to work as it is the Gantt configuration. The Undo extension works only with the data: tasks, links, resources, and resource assignments:

If you want to undo or redo something in the Gantt configuration, you will need to implement a custom solution by using the Gantt API and Javascript.

However, if you mean that when you change the zoom levels, the Undo doesn’t work, I couldn’t reproduce the issue in the following snippet:

If you can reproduce the issue in the snippet, you can give me the steps to do that.
Otherwise, you can add your configuration to the following snippet and make sure that the issue is reproduced there:

Then, click on the Save button and send me the link.
Or send me a ready demo with all the necessary JavaScript and CSS files so that I can reproduce the issue locally.
