Checking JS types does not accept @implements or @augments on constructor functions

TypeScript Version: 3.9.5 (also tested on 3.9.3 initially)

Search Terms: @implements, jsdoc

Code

/**
 * @param {string} name
 * @implements {EventTarget}
 * @constructor
 */
function Foo (name) {
  this.name = name
}

/**
 * @param {string} type
 * @param {EventListenerOrEventListenerObject} listener
 * @param {boolean | AddEventListenerOptions} [options]
 */
Foo.prototype.addEventListener = function (type, listener, options) {}

Then run tsc --noEmit --checkJS --allowJS reproducer.js

Expected behavior:

According to https://www.typescriptlang.org/docs/handbook/type-checking-javascript-files.html#constructor-functions-are-equivalent-to-classes, constructor functions are treated like classes. So using @implements or @augments on them should be possible. It used to work in the past.

Actual behavior:

reproducer.js:6:10 - error TS8022: JSDoc '@implements' is not attached to a class.

6 function Foo (name) {
           ~~~


Found 1 error.

Playground Link: I was not able to reproduce this in the playground (but it does not have the latest 3.9 versions available)

Commencez par l’exemple reproducer.js et exécutez tsc --noEmit --checkJS --allowJS reproducer.js avec la version affectée de TypeScript. Suivez le traitement de JSDoc @implements et @augments sur les fonctions constructrices ; le travail est terminé lorsque les annotations sont acceptées sans TS8022 et que les vérifications JavaScript existantes restent valides.
