Preview should either fully support PDF Portfolios or not preview them at all
When our users try to preview a PDF Portfolio document, they see the message "For the best experience open this PDF Portfolio in Acrobat X..." Which is fine since it isn't supported in preview.
However, if the user refreshes the page, it generates a preview for only the first page so then users think that the other content is lost.
If this file type is not supported then no preview showing is better than a partial preview which confuses users.
