Array.from doesn't work with some iterables #359
Description
Consider the following code.
const l_array = ['a', 'b', 'c'];
const l_it = l_array[Symbol.iterator](); //convert to iterator
var result = Array.from(l_it);
When that code is called from JavaScript's native Array.from, the result is ['a', 'b', 'c']
When that function is called from prototype.js Array.from, the result is []

This also breaks Google Maps (new today or very recently?). Removing the
Array.from = $Aline fixes Google Maps, but I'm not sure if I've broken any of my other ancient Prototype code.
