Describe the bug

How to reproduce the bug? 1.Disable the undo manager by invoking um.stop(). 2.Make alterations to the content. 3.Re-enable the undo manager using um.start().

What is the expected behavior? When the undo manager resumes, any modifications made after its pause should be treated as a single change. This ensures that clicking "undo" will revert the entire set of alterations to the state prior to the undo manager's interruption.

What is the current behavior? The changes made after undomanager stopped is not included as change after it is resumed.Upon selecting the undo option, the changes persist and are not rolled back as expected.

Also i have tried added the change to the undomanager : var components = editor.Components; editor.UndoManager.add(components.getComponents().models);
