Steps to Reproduce

3. Login and click on My Dashboard under the dropdown in the upper-right corner.
4. Go to Admin -> Content
5. Go to Documents and Media and upload a PDF with semi unique title for searching purposes and set viewable by power user
7. Search for the document
8. Click on the document in the search results
expected result: document will be displayed and no console error is thrown
