project_dir does not work

[Shrews]

Setting project_dir in the interface.run() method does not appear to work. Example:

r = ansible_runner.run(
        private_data_dir='demo',
        playbook='test.yml',
        project_dir='my_project',
)

This should find the demo/my_project/test.yml playbook, but instead fails with:

ERROR! the playbook: test.yml could not be found

Also, it appears to not modify the directory it passes to podman as the working directory. Even with "project_dir" specified, podman is still invoked with:

execve("/usr/bin/podman", ["/usr/bin/podman", "run", "--rm", "--tty", "--interactive", "--workdir", "/runner/project", "-v", ...

and if the 'project' directory does not exist in private_data_dir, will throw an error of Error: workdir "/runner/project" does not exist on container ...
