Filebeat Autodiscover Hints Breaking Template

Hey @exekias,

I have managed to almost achieve what I was after. I've been able to use the hints autodiscover to only publish logs with a specific annotation, whilst also being able to make use of multiline hints:

    filebeat.autodiscover:
      providers:
        - type: kubernetes
          hints.enabled: true
          include_annotations: [logging']

    processors:
    - add_cloud_metadata: ~
    - drop_event:
        when:
          not:
            equals:
              kubernetes.annotations.logging: 'true'

The last thing I'm struggling to get working is tail_files within the Kubernetes autodiscovery (Since our filebeat instances are stateless). Currently when a filebeat restarts it ends up scraping logs that have already been scraped, resulting in duplicated messages being published.

Is there somewhere I can configure the hints discovery/kubernetes logger to only tail files?
Neither of the below configs appear to work:

    filebeat.autodiscover:
      providers:
        - type: kubernetes
          hints.enabled: true
          include_annotations: ['logging']
          config:
            - type: docker
              tail_files: true

    processors:
    - add_cloud_metadata: ~
    - drop_event:
        when:
          not:
            equals:
              kubernetes.annotations.logging: 'true'
    filebeat.autodiscover:
      providers:
        - type: kubernetes
          hints.enabled: true
          include_annotations: ['logging']
          tail_files: true

    processors:
    - add_cloud_metadata: ~
    - drop_event:
        when:
          not:
            equals:
              kubernetes.annotations.logging: 'true'
