--- Comment #3 from Diego Pino <dpino at igalia.com> ---
The same change is necessary for Set. According to the ES6 spec [1]:

"callbackfn is called with three arguments: the first two arguments are a value contained in the Set. The same value of passed for both arguments. The Set object being traversed is passed as the third argument."
