vars_prompt with private: false doesn't show the prompt before waiting for input?

[liamjones]

I'm writing a molecule test that needs some vars from either user input if being run manually, or --extra-vars if being run in CI. Some are private, others aren't.

As a result, I have this in converge.yml:

  vars_prompt:
    - name: item_1
      prompt: Value for item_1
      private: no
    - name: item_2
      prompt: Value for item_2
      private: yes

If I run this, I get the usual molecule output to start with:

...
INFO     Dependency completed successfully.
INFO     Running default > create
WARNING  Skipping, instances already created.
INFO     Running default > prepare
WARNING  Skipping, instances already prepared.
INFO     Running default > converge
INFO     Sanity checks: 'docker'

And then it stops and waits for input without displaying any prompt.
If I blindly answer the prompt I'm then shown the prompt for item_2, the private one and can answer that.
after answering prompt two, I then see the prompt for item_1 output! Like so:

INFO     Running default > converge
INFO     Sanity checks: 'docker'
a
Value for item_2: 
Value for item_1:
PLAY [Converge] ****************************************************************

ok: [app-server]

ok: [app-server] => {
    "item_1": "a"
}

TASK [debug 2] *****************************************************************
ok: [app-server] => {
    "item_2": "b"
}

Is this a molecule bug? Any ideas on workarounds?
