I didn't realize sort() sorted in place. Lets follow the way sort() works and
revert this.

I spoke to one of the members of our team and he did not feel we should alter
this function. Lets revert this and adhoc it. (see other comment)

   for (var key of this.keys()) {
     var value = this.get(key);
     result.set(value, key);
   }
   return result;
