_preserved

protected _preserved: Map<string, unknown>

When the ymap is not connected to the doc, its value cannot be read. But we need to use those value during the creation, so the yfied decorated field's value will be stored in this map too during the creation.

After the ymap is connected to the doc, this map will be cleared.
