It very obviously does otherwise we wouldn't have this bug report.

Even if it's technically correct, we currently have 2 uses for sub-class-of, either it's a functional sub-class (video/mp4 is a sub-class of video/quicktime, so an app that handles quicktime should handle mp4), or it's a detection sub-class (like in the case of XML and ZIP file based file types).

I don't think it's wrong either, and you can still do that by renaming the file to .zip and opening it.
