Cannot parse Flow $Shape

Reproduce el fallo con el ejemplo proporcionado components/Label.js e inspecciona los puntos de entrada del análisis de Flow de react-docgen; en el issue no se menciona ningún archivo fuente ni ninguna prueba. Se considera terminado cuando se analizan las props envueltas en $Shape y se devuelven los metadatos de props mostrados para el tipo sin envolver, con cobertura para este ejemplo.

I don't know whether this applies to all Flow utility types in general, but React makes extensive use of $Shape (and so do we!) - react-docgen (3.0.0-rc.1) seems to fail at parsing this.

Example component props:

// components/Label.js
type Props = $Shape<{
	/** Content to place inside .ui.label element */
	children?: React.Node,
	/** Classes for .ui.label element */
	classes?: string,
	/** Type of the label (icon, favicon, image, notification, state) */
	type?: 'icon' | 'favicon' | 'image' | 'notification' | 'state',
	/** Tooltip (data-content, data-position, data-delay) */
	tooltip?: Tooltip
}>;

With $Shape:

{
    "displayName": "Label",
    "methods": []
}

Without $Shape:

{
	"displayName": "Label",
	"methods": [],
	"props": {
		"children": {
			"required": false,
			"flowType": {
				"name": "ReactNode",
				"raw": "React.Node"
			},
			"description": "Content to place inside .ui.label element"
		},
		"classes": {
			"required": false,
			"flowType": {
				"name": "string"
			},
			"description": "Classes for .ui.label element"
		},
		"type": {
			"required": false,
			"flowType": {
				"name": "union",
				"raw": "'icon' | 'favicon' | 'image' | 'notification' | 'state'",
				"elements": [
					{
						"name": "literal",
						"value": "'icon'"
					},
					{
						"name": "literal",
						"value": "'favicon'"
					},
					{
						"name": "literal",
						"value": "'image'"
					},
					{
						"name": "literal",
						"value": "'notification'"
					},
					{
						"name": "literal",
						"value": "'state'"
					}
				]
			},
			"description": "Type of the label (icon, favicon, image, notification, state)"
		},
		"tooltip": {
			"required": false,
			"flowType": {
				"name": "Tooltip"
			},
			"description": "Tooltip (data-content, data-position, data-delay)"
		}
	}
}
