jsdoc @type is not working properly for some class method variant

TypeScript Version: 4.0.0-beta and 3.9.2

Search Terms: jsdoc, type, typedef, class method, typechecking

Code

// @strict: false

/**
 * @typedef {(newNumber: number) => void} SetNumberFunc
 */

class A {
    /**
     * @type {number}
     */
    a = 0;

    constructor() {
        this.a = 0;
    }

    /**
     * @type {SetNumberFunc}
     */
    setAVariant1(newNumber) {
        this.a = newNumber;
    }
}

Expected behavior: The newNumber param should have a number type when hovering on the setAVariant1 method.

Actual behavior: The newNumber param have any type when hovering on the setAVariant1 method.

从链接的 TypeScript Playground 复现开始，检查如何处理类方法 setAVariant1 的 JSDoc @type 注释。将 newNumber 的悬停类型与预期的 number 类型进行比较，并验证修复完成后，复现结果报告的是 number 而不是 any。
