Polyfills are enumerable in PhantomJS

[waabid]

Running the following code in PhantomJS:

var x = []; for (var y in x) { console.log(y) };

yields

find
includes

in the console.

If the functions are set via Object.defineProperty, you can specify enumerable property (you don't actually have to; it defaults to false).
