Document preview thumb nails no longer work as expected
Prior to the AWS migration, media library items marked as documents (PDF, MS Word, etc.) used to have a thumbnail preview icon (cover art, first page of the document, etc.) and on their document page. Documents uploaded prior to the AWS migration still have this feature, but new documents do not.
Examples: Pre-AWS document https://csd.wisc.edu/an-introductory-guide-to-research-ethics/ https://csd.wisc.edu/phd-requirements-checklist/
Post-AWS document https://csd.wisc.edu/2018-2019-ms-student-handbook/
The thumbnail on the document page was clickable, allowing the user to easily select the document.
