Could not disable ssh-rsa in gitlab-ssh

I am trying to disable ssh-rsa algorithm for public key in gitlab-ssh, but without success.

gitlab_sshd['public_key_algorithms'] in gitlab.rb is set like this:

gitlab_sshd['public_key_algorithms'] = ['ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384', 'ecdsa-sha2-nistp521', 'ssh-ed25519', 'rsa-sha2-256', 'rsa-sha2-512']

It also looks like correct config is generated:

sshd: {"concurrent_sessions_limit":100,"proxy_protocol":true,"proxy_policy":"use","proxy_header_timeout":"500ms","grace_period":55,"client_alive_interval":null,"ciphers":null,"kex_algorithms":["curve25519-sha256","curve25519-sha256@libssh.org","ecdh-sha2-nistp256","ecdh-sha2-nistp384","ecdh-sha2-nistp521"],"macs":["hmac-sha2-256-etm@openssh.com","hmac-sha2-512-etm@openssh.com","hmac-sha2-256","hmac-sha2-512"],"public_key_algorithms":["ecdsa-sha2-nistp256","ecdsa-sha2-nistp384","ecdsa-sha2-nistp521","ssh-ed25519","rsa-sha2-256","rsa-sha2-512"],"login_grace_time":60,"host_key_files":["/var/opt/gitlab/gitlab-sshd/ssh_host_ecdsa_key","/var/opt/gitlab/gitlab-sshd/ssh_host_ed25519_key","/var/opt/gitlab/gitlab-sshd/ssh_host_rsa_key"],"host_key_certs":[],"listen":"[::]:2222","web_listen":"localhost:9122"}

And even log when starting SSH server looks good:

{"correlation_id":"XXXX","level":"info","msg":"Listening for SSH connections","supported_public_key_algorithms":["ecdsa-sha2-nistp256","ecdsa-sha2-nistp384","ecdsa-sha2-nistp521","ssh-ed25519","rsa-sha2-256","rsa-sha2-512"],"tcp_address":"0.0.0.0:2222","time":"XXX"}

But nmap stills shows ssh-rsa as supported algorithm:
