Content Server OPDS feeds: no link for kfx files

[Joe]

Version: 7.12
OS: Linux, Windows 10 (haven't tested on macOS)

Both of the following examples (stripped to save space & be anonymous) should also list the imported KFX as a download link not sure if the type should be "application/x-mobi10-ebook" or something else but it is definitely missing.

  <entry>
    <title>Book Title</title>
    <author>
      <name>author name</name>
    </author>
    ....
    ....
    </content>
    <link type="application/x-mobi8-ebook" href="/get/azw3/603/CalibreLibrary" rel="http://opds-spec.org/acquisition" length="395032" mtime="..."/>

The Content Server website shows them properly and you can download them that way but not through OPDS

{"formats": ["KFX"], "format_sizes": {"KFX": 1444220}, "aut.... ...."id": 661}
