Nested type assertions in JS code are broken

**Prettier 1.19.1**

When using type assertions, **TypeScript** sometimes requires an intermediate cast to `unknown` due to a lack of significant overlap between types.

**Prettier’s** formatting currently breaks this intermediate JSDoc‑based type assertion.

## Input:
```js
const BarImpl = /** @type {BarConstructor} */ (
	/** @type {unknown} */
	(function Bar() {
		throw new Error("Internal error: Illegal constructor");
	})
);
```

**Note:** `BarImpl` is wrapped by a `Proxy` later in the code, which takes care of the actual `apply` and `construct` calls, but that’s irrelevant to this issue.

## Output:
```js
const BarImpl /** @type {BarConstructor} */ =
	/** @type {unknown} */
	(function Bar() {
		throw new Error("Internal error: Illegal constructor");
	});
```

## Expected behavior:
```js
const BarImpl = /** @type {BarConstructor} */ (
	/** @type {unknown} */
	(function Bar() {
		throw new Error("Internal error: Illegal constructor");
	})
);
```
