@Adriaan thanks for providing some minimal steps to reproduce the problem, I indeed can reproduce it. Interestingly reversing the two sshd_config lines, like this:
Port 7722 Include /etc/ssh/something_else causes sshd to listen only on port 7722. I think this is an upstream OpenSSH bug, and should be reported to the upstream portable OpenSSH bug tracker: https://bugzilla.mindrot.org/ I had a look at the existing bugs but only found this one related to the Include functionality: https://bugzilla.mindrot.org/show_bug.cgi?id=3122 It's a problem specific to Match stanzas, so I don't think it applies here, however it tells us there are probably still some edge cases to iron out. Do you think you can follow up and file a bug upstream? If you do, please link to it here.
