Comment on attachment 398789 [details] Patch (In reply to Joseph Pecoraro from comment #2) > Something like this should really have a test. Unfortunately, this is deep inside View code :( Unless you're referring to tests of `parseMIMEType` itself, which we currently don't have any of (but I could add).
