Regression from Strada: IntelliSense does not work properly inside `{}` following `@throws`

[tats-u]

Steps to reproduce

Prepare:

interface ApiResponse {
  downloads: number;
  start: string;
  end: string;
  package: string;
}

/**
 * Fetch the number of downloads for a given npm package in the last month.
 * @param packageName The name of the npm package to fetch download data for.
 * @returns A promise that resolves to the number of downloads in the last month.
 * @throws {TypeError} If the fetch request fails or returns a non-OK status.
 */
export async function fetchDownloadsLastMonth(packageName: string): Promise<number> {
  const response = await fetch(`https://api.npmjs.org/downloads/point/last-month/${packageName}`);
  if (!response.ok) {
    throw new TypeError(`Failed to fetch data: ${response.status} ${response.statusText}`);
  }
  return (await response.json() as ApiResponse).downloads;
}

Almost all of the above code is generated by Copilot inline completion (slop).

1. Remove TypeError in the brackets after @throws
2. Type "Ty" at the same place

Behavior with typescript@6.0

"TypeError" appears in the IntelliSense and you can select it.

Behavior with tsgo

"TypeError" does not appear in the IntelliSense.
