SSH Kitten ignores config file

Describe the bug I setup a minimal kitty config in $HOME/.config/kitty/kitty.conf which works as expected. However I want to specify a custom login shell for a specific remote host so I followed https://sw.kovidgoyal.net/kitty/kittens/ssh/#login-shell-environment and created the $HOME/.config/kitty/ssh.conf accordingly - it contains 2 lines

hostname hostname.example.com
login_shell zsh

However even after I started a fresh kitty instance, the ssh.conf seems to be ignored completely.

When I specify the loginshell inline it works as expected kitten ssh hostname.example.com --kitten login_shell=zsh

To Reproduce Steps to reproduce the behavior:

Install kitty 0.35.2
Ensure kitten is also version 0.35.2
Ensure $HOME/.config/kitty is recognized by kitty
Create $HOME/.config/kitty/ssh.conf
Observe the ssh-kitten config not being used
