Plugin - files are still listed from previous search when switching to a search with no results.
When switching active searches to a search that has no results, the files from the previous view search are still listed, but the users list is properly cleared.
To replicate, perform two searches - one that has results and one that does not. Click on a user in the search that has results to view their search results. Next, switch to a search that has no results. You will see the files from the previous search still listed.
