Perspective Component Example Properties

I’ve been unable to get my custom Perspective component to populate with example properties (properties that can be deleted and don’t show back up after the view is closed and reopened).

Previously, (8.0.1 ish) it was working by just changing “default” to “example” like this

        "labels": {
            "type": "array",
            "description": "Labels for the columns",
            "example": ["January", "February", "March", "April", "May", "June", "July"]
        },

but this same format is not working with SDK 8.1.0. Properties don’t seem to populate unless they’re marked “default”. I’ve tried fully defining the array items like this

        "labels": {
            "type": "array",
            "items": {
                "type": "string",
                "description": "Label for a specific column"
            },
            "description": "Labels for the columns, respective of order in data",
            "example": ["January", "February", "March", "April", "May", "June", "July"]
        },

but no change.

Is there anything else I need to do to achieve example-like behavior for properties?
