Dexie cloud add() operator sync bug

[NitroRCr]

Reproduction

There is a message object in the table messages
Its contents.0.items was initially an empty array

Execute this:

await db.messages.update('<messageId>', {
  'contents.0.items': add([item])
})

It works fine. The item has been added.

It also triggers sync at the same time, with payload:

Bug when receiving the response:

                                        ]
                                    }
                                }

            ]
        }
    ],
    "rejections": [],
    // ...
}

The message changed again, and content.0.items became a object with property add:

This is not an expected behavior. I guess it is a bug of dexie-cloud
