KumoMTA doesn't enclose the display name in quotes

When using the HTTP API, KumoMTA doesn’t enclose the display name in quotes, resulting in errors. Example:

    'text_body': body['text'],
    'html_body': body['html'],
    'from': {
        'email': 'test@example.org',
        'name': 'Special, char,acters! $$ he, he'
    }
}

This results in the following header:

Is this intended behavior, or do I need to manually enclose the display name in quotes?
