Example JavaScript with JSDoc

💻 Code

/**
 * @typedef A
 * @property {string} a
 */

/**
 * @typedef B
 * @property {number} b
 */

class Base {
    /**
     * @type {A}
     */
    value;
}

class Test extends Base {
    /**
     * @type {A & B}
     */
    value;
}

🙁 Actual behavior

The declaration file does not contain a typing for the narrower type for value in class Test.

declare class Test extends Base {
}

🙂 Expected behavior

The declaration file should contain the narrower type for value.

declare class Test extends Base {
    /**
     * @type {A & B}
     */
    value: A & B;
}

This bug is especially problematic when creating APIs with function overloads for event register functions, because it breaks what has been described in #25590 (comment).

I am trying to git bisect this bug but I am not able to build older versions of typescript or to run tests on older versions. Does this have to do with the dependency versions? This has to do with the dependency versions. Could someone give me a pointer on how to install the right ones?
