Summary [Attachment Support] Cloned attachment elements lose their unique identifiers

When using cloneNode() to clone an attachment element, the resulting attachment element's `uniqueIdentifier` will be the empty string, rather than the original attachment element's unique identifier. Currently, WebKit clients (e.g. Mail) work around this by saving the original attachment's unique identifier to a temporary attribute prior to cloning. Ideally, clients shouldn't need to hack around this for nodes that never appear in the document, since the attachment unique identifier is only guaranteed to uniquely identify attachment elements that are connected to the document.
