Is `host.name.edu:XXXX` an invalid format for an `.ssh/config` file?

I have weird case where I'm being told my IT to use the port inside the ssh URL to connect to a git server. My original ssh config is the following:

Host my-host-alias
  HostName redacted.redacted.edu
  Port 2222
  User git
  IdentityFile ~/.ssh/my-ssh-private-key

and I was using the git remote url ssh://git@my-host-alias/path/to/repo.git. I was getting some weird Auth errors with that config (though basic functionality was still working) so IT instructed me to use the git remote url ssh://[email protected]:2222/path/to/repo.git and that appeared to work with a manually specified GIT_SSH_COMMAND='ssh -i ~/.ssh/my-private-ssh-key. So I reconfigured my .ssh/config as follows:

Host redacted.redacted.edu:2222
  IdentityFile ~/.ssh/my-ssh-private-key

Suddenly, it seems as if ssh can't parse the Host entry anymore. If I run ssh -Tvvv ssh://[email protected] I get the following output (snippet):

debug1: /Users/myuser/.ssh/config line 94: Applying options for *
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 48: Applying options for *
debug1: /etc/ssh/ssh_config line 52: Applying options for *

It appears that specifying a Host with a port in the URL breaks the parsing of .ssh/config. Can someone verify this?

The SSH URI syntax won't use ~/.ssh/config

The SCP syntax used by OpenSSH (1999), from the history of the SSH protocol, predates URI (finalized with RFC 3986, January 2005)

So you need to use my-host-alias:path/to/repo.git if you want to use .ssh/config.
