#U interpolation doesn't work when using ~/.ssh/config

[Oliveiras]

Tmux version: 3.0a

Description
#U only knows my ssh username when I use it in ssh command, but not when I save the username in the ~/.ssh/config file.

How to reproduce
If I connect using ssh my_remote_user@another_host everything works.
Now, write the following to the file ~/.ssh/config :

Host dev_server
    Hostname another_host
    User my_remote_user

And connect using ssh dev_server .
#U doesn't get updated.

Possible Solution
I don't know if there is a solution. If not, just write this limitation in the README.
