Description

Currently, the flatten function seems to not flatten the attributes of nested objects within a slice, but rather leaves the objects within the slice unchanged.

Steps to Reproduce

Consider the following input for the flatten function:

{
  "things": [
    {
       "name": "a"
    }
  ]
}

And use the flatten function:

flatten(attributes)

Expected Result

The result should be fully flattened:

{
  "things.0.name": "a"
}

Actual Result

The index of the individual objects within the slice is put into the attribute keys (which is expected), however the flattening is not applied to the nested objects:

{
  "things.0": {
    "name": "a"
  }
}
