Service: scene.turn_on not working with Spotify (but works with TuneIn)

I wrote a automation that when the mailman opened my mailbox.
I get a notification on my Google Home(s), but if music was playing that would stop.
To restart I save the state as scene before playing the message
And restarts with [service: scene.turn_on].
This works now when i stream Radio to TuneIn, but for some reason this does not work with Spotify !?

Anyone have an idea why, and how to solve?

- id: 'mailbox_full'
  alias: 'MailBoxFull'
  description: 'Mailbox lid has been opened'
  trigger:
  - entity_id: binary_sensor.mailbox 
    from: 'off'
    platform: state
    to: 'on'
  condition: []    
  action:
  - data:
      scene_id: mailbox_notification_revert
      snapshot_entities: 'media_player.woonkamer,media_player.nestmini7404'
    service: scene.create 
  #- delay: 00:00:04
  - data:
      entity_id: media_player.woonkamer
      message: "You Got Mail"  
    service: tts.google_say  
  - delay: 00:00:08   
  - data:
      entity_id: scene.mailbox_notification_revert
    service: scene.turn_on  

I notice that the “snapshot_entities:” does not saves the attributes.
Is it even possible to save and restore the attributes?
