 In tree mode, invalid JSON is automatically repaired when loaded. When the repair was successful, the repaired contents are rendered but not yet applied to the document itself until the user clicks "Ok" or starts editing the data. Instead of accepting the repair, the user can also click "Repair manually instead". Invoking `.acceptAutoRepair()` will programmatically accept the repair. This will trigger an update, and the method itself also returns the updated contents. In case of `text` mode or when the editor is not in an "accept auto repair" status, nothing will happen, and the contents will be returned as is.
