JSDoc Object literal not parsed ignoring leading star, leading to parse error

[weswigham]

Code
allowJs and checkJs are on.

/** @typedef {{
 *     type: string,
 *     header: {text: string},
 *     longestChain: {duration: number, length: number, transferSize: number},
 *     chains: !Object<string, !CriticalRequestChainRenderer.CRCNode>
 * }}
 */
CriticalRequestChainRenderer.CRCDetailsJSON; // eslint-disable-line no-unused-expressions

Expected behavior:
A strongly typed CriticalRequestChainRenderer.CRCDetailsJSON

Actual behavior:

front_end/audits2/lighthouse/renderer/details-renderer.js(294,2): error TS1131: Property or signature expected.

(An error on the first leading * in the comment-embedded object literal.)
