Nested type descriptions

Sorry if this has been reported before in some form before, but is there currently support for nested type descriptions? For example, given the following structure (using Flow and react-docgen@5.3.1):

type Panel = {
	/** Panel title */
	title: string,
	/** Panel content */
	content: string,
	/** Sublevels of more Panels */
	panels: Array<Panel>
};

type Props = {
	/** One or more toggleable Panels */
	panels: Array<Panel>
}

/** Hello World! */
const Component = (props: Props) => { ... }

^ Does not generate any description for the Panel -props. Is this intentional? The output for a Panel is:

{
	"name": "signature",
	"type": "object",
	"raw": "{ ... }",
	"signature": {
		"properties": [
			{
				"key": "title",
				"value": {
					"name": "string",
					"required": true
				}
			},
			{
				"key": "content",
				"value": {
					"name": "string",
					"required": true
				}
			},
			{
				"key": "panels",
				"value": {
					"name": "Array",
					"elements": [{ "name": "Panel" }],
					"raw": "Array<Panel>",
					"required": true
				}
			}
		]
	}
}

Start by reproducing the Flow example from the issue with react-docgen@5.3.1 and inspect the generated signature for Panel. No source files or tests are named in the report; done means the nested Panel properties retain their descriptions in the generated output, with coverage for the shown structure.
