In salt what causes the WARNING 'version' argument will be ignored for multiple package targets

Question

For some of my pkg.installed states I get this warning

[INFO ] Executing state pkg.installed for [install haproxy package]

[WARNING ] 'version' argument will be ignored for multiple package targets

I am not specifying a 'version' argument though.

My state looks like this:

"install haproxy package":
  pkg.installed:
    - pkgs:
      - haproxy

Why am I getting this warning and how do I get rid of it?

This turned out to be a bug in salt version 3006.1. See bug report https://github.com/saltstack/salt/issues/64563.
