Missing optional JSDoc param parsing

[eMerzh]

Hello,

we are in the process in porting our jsx codebase to ts, we are getting there, but there are still some JS[X] files that need to be rewritten

In the mean time, we are relying on jsdoc to [very] pseudo type the remaining files,

with something like this :

/**
 * @param {Object} props
 * @param {string|null} [props.hint]
 * @param {ReactNode} props.value
 * @param {number} [props.iconSize]
 * @param {string} [props.className]
 * @param {boolean} [props.preventDefault]
 * @param {boolean} [props.external]
 * @param {string} [props.schemaBuiltinKey]
 *
 */
const AttributeStringHint = ({ hint, value, iconSize = 14, className, preventDefault, external, schemaBuiltinKey }) => {

note the [ ] , that mark the prop as optional here in the react component

then if i can from a tsx file like this
<AttributeStringHint key={index} hint={attr.hint} value={value} />
i got with the current preview

Attribute.tsx:160:8 - error TS2739: Type '{ key: number; hint: SchemaAttributeHint | null | undefined; value: string; }' is missing the following properties from type '{ className: any; external: any; hint: any; iconSize?: number | undefined; preventDefault: any; schemaBuiltinKey: any; value: any; }': className, external, preventDefault, schemaBuiltinKey

160       <AttributeStringHint key={index} hint={attr.hint} value={value} />

in current ts, everything is ok of course

I had though this was working, but JS support is still pretty WIP.
