Parameter "timeout" of module "ansible.builtin.wait_for_connection" is ignored

[setpill]

We have a task at the start of every deployment that tests for the presence of legacy credentials. It is of the form:

- name: Determine hosts with "{{ legacy_user }}" credentials
  ansible.builtin.wait_for_connection:
    timeout: 1
  register: legacy_reachable
  ignore_errors: yes
  vars:
    ansible_user: "{{ legacy_user }}"
    ansible_password: "{{ legacy_pass }}"

Without mitogen, this task returns in 1 second. With mitogen, it takes over 1 minute.

I had hoped a #1200 might fix this, however even with mitogen 0.3.22 it is still slow.
