Puppet agent runs in environment specified on CLI when not in an agent specified environment

Desired Behavior: 

In Puppet 6.24 the behaviour is as expected, if a CLI environment is specified but the agent is not in a agent specified node group the run outputs a notice and continues in the server specified environment:

[root@pe-node-48716e-0 ~]# puppet agent -t --environment=testing

Notice: Local environment: 'testing' doesn't match server specified node environment 'production', switching agent to 'production'.

Actual Behavior:

After upgrading to 6.25 it runs in the CLI specified environment:

[root@pe-node-48716e-0 ~]# puppet agent -t --environment=testing

Info: Using environment 'testing'
