💻 Code

/**
 * @template T1
 * @typedef {T1} TakesT1
 */

/**
 * @template T1
 * @template T2
 */
class Foo {
    /**
     * @template T1
     * @template {TakesT1<T1>} T2
     *                    ^^--- Static members cannot reference
     *                          class type parameters.(2302)
     * @param {T1} t1
     * @param {T2} t2
     */
    static bar(t1, t2) {

    }
}

🙁 Actual behavior

"Static members cannot reference class type parameters." This is wrong because the equivalent typescript for this situation does not give an error: playground.

🙂 Expected behavior

No ts2302 error, TakesT1<T1> should use the T1 generic from the static bar() method, rather than from the Foo class.

A workaround for this is to rename the generic so that it doesn't have the same names as class.
