Synchronization undo history between multiple Editor instances

1

I have two instances of the Editor. The first is the main editor, and the second is a duplicate modal editor that expands to full screen. Is there any way to synchronize the undo history between these two instances?

According to the documentation, I know that I can serialize the state by using toJSON in one editor and then deserialize it using fromJSON in the other. However, the state.toJSON() method does not serialize the undo history.

I tried to save the unserialized state and then apply it to another editor using view.updateState() , but this caused errors due to mismatched transactions and position out of range.

The undo history does not current support JSON serialization.

Putting an existing state into a new editor should work fine, though.
