Enabling Experiments or Education Features in the Ore UI Edit World menu does not create a copy of the world

Summary:
In the JSON Edit World menu, enabling an Experiment or the Minecraft Education Features toggle would create a copy of the world with the selected toggle enabled, leaving the original world unchanged. In the Ore UI Edit World menu, this behavior no longer occurs.

Steps to Reproduce:

1. Create a new world.

2. Exit the world.

3. Click the pencil icon on the world.

4. Enable the Minecraft Education Features toggle under the Cheats tab, or enable any Experiment under the Experiments tab.

5. Save your changes and return to the Worlds menu.

Observed Results:
The toggle is enabled directly on the original world, and a copy of the world is not created.

Expected Results:
A copy of the world should be created, with the toggle enabled only on that copy while the original world remains unchanged.
