    - **Added:** Nested attachments are now supported for Email and Pdf formats.
      - Attachments will use the same PdfOutputOptions.Watermarks and PdfOutputOptions.FastWebViewEnabled properties
        from root container document for PDFs generated for attachments.
      - Some emails may contain extensionless attachments which are nested emails, these are "message/rfc822" attachments.

      - On attachment tooltips, desciption will shown as "DispositionType (ContentType)" e.g "attachment (application/octet-stream)".
      - On attachment tooltips, the last modified date will also be shown (for PDF Portfolio and Email attachments when available).
