artifact ignored due to failing content validation is logged as cached in feed

If enabled "File content validation" for a proxy repo for Maven central. Nexus retrieves files through a virus scanner, which returns html error page for some artifacts.
Nexus correctly ignores these invalid downloaded files (the error page) as I can't see it cached, but in the feeds (e.g. CachedArtifacts) is says that the artifact was cached. This is not correct.
