Persistent Notification notify in a group not working

so if i have Persistent Notification in a notify group as such:

  - platform: group
    name: nate
    services:
      - service: mobile_app_nate
      - service: notify
      - service: persistent_notification

and I want to group together notification like:

    - service: notify.nate
      data:
        title: Title Test Notification
        message: The Test Notification Message POOL
        data:
          group: Pool

the data: group: Pool prevents the Persistent Notification from notifying

anyway to make this work without have 2 completely separate notification services?

even if group data isn’t being used by Persistent Notification (yet i hope), I don’t see what the extra data would prevent it from sent/displayed.
