(IE11) array.prototype.find adds 'find' key

[Pzenarch]

Adding the 'Array.prototype.find' script - under IE11 - causes 'find' to be returned as a key when looping through any array, even an empty one.

var x = []; for( var key in x ) console.log(key);

The above code logs 'find' to the console, only when the shim is added however. I suspect looking at the code that other array shims will have a similar impact.

Hi @Pzenarch. I updated Array.prototype.find polyfill with the latest changes from MDN. Please try with this version:

npm install mdn-polyfills@canary

it's also available here https://cdn.jsdelivr.net/npm/mdn-polyfills@5.20.1-canary/Array.prototype.find.js

Let me know if it's working.
