leaky environment stuff from ansible-runner, just wanted to get a concrete test case established here.

I just ran into this issue trying to run Molecule in AAP where my playbook calls molecule create, molecule converge, molecule verify, etc. Outside of AAP, it occurred when I launched with ansible-runner, but not with ansible-playbook.
