IE11 Polyfill: Array.protoype.includes property is enumerable

[apapko]

Array.prototype.includes property is enumerable. IE11 Console: Object.getOwnPropertyDescriptor(Array.prototype, 'includes') ---> reveals:

enumerable: true,
configurable: true,
writable: true

Should be: {writable: true, enumerable: false, configurable: true}

Please correct the following polyfill

From:
Array.prototype.includes = function includes(searchElement /, fromIndex/ )
To:
Array.prototype.includes = Object.defineProperty( Array.prototype, 'includes', {
configurable: true,
writable: true,
value: function includes(searchElement /, fromIndex/ ) {...}
})
( enumerable: false, is the default value )
