💻 Code

export const foo = {
    num: 0,
    f(param: typeof this.num, f: typeof this) {
        const x = this;
        type X = typeof x;
        //              ^
        type Y = typeof this;
        //              ^^^^
    }
}

🙁 Actual behavior

move the cursor to this, it shows any

🙂 Expected behavior

like typeof x, it should show { number: number, f... }
