Subject: [PATCH] Updates: Try a more compatible method to detect if a file
 exists when using the FTP Extension. This change causes it to list the parent
 directories files, and assets that the node exists within the returned
 listing, this is a little more compatible than relying upon the FTP server to
 correctly filter the returned resultset to the specific file/node being
 requested. Fixes #28013
