Getting "Minimized source" in results from getDashboard

I'm calling getDashboard() in the CloudWatch API and I'm getting results like this:

  [
    'CWAgent',
    'mem_used_percent',
    'host',
    'ip-172-31-51-95',
    { label: 'default', region: 'us-west-2' }
  ],
  [
    '...',
    'ip-172-31-15-69',
    { label: 'redwood', region: 'us-west-2' }
  ],
  [
    '...',
    'ip-172-31-7-189',
    { label: 'yellowstone', region: 'us-west-2' }
  ],
]

I recognize the '...' fields from the "Minimize source" option in the web interface, but surely it's a bug to be minimizing the results in the API call. Right?
