please see code

    let a = new Promise(resolve=>resolve(1))
    let b = new Promise(resolve => resolve(a))
    console.info(a === b)           // false

    b = Promise.resolve(a)
    console.info(a === b)            // true

when run code, we will get false and true. what is difference?

My key point：when we input thenable or Promise for resolve of new Promise(resolve => resove())，what happened？
