Methods not getting added in Edge

[freon27]

Hi, we're using the polyfill in our Angular app (thanks!) and it's working great for IE11 and iOS. The company I'm working at are currently stuck on the following Edge version:

Microsoft Edge 41.16299.1419.0 Microsoft EdgeHTML 16.16299

We're creating an empty FormData object with new both with and without a form element as parameter. When we try to use .has we get an error that it's not a function. Investigating the prototype, we see that the object only has append and constructor which matches what was natively implemented in this version so it seems like the polyfill isn't being applied at all. We tried updating the polyfill to the latest version but it's not made any difference.

I've looked though the previous issues related to Edge but couldn't see this issue. Any ideas?

maybe something wrong with this condition? https://github.com/jimmywarting/FormData/blob/e52a90ceb2e3424e5e2203760ecaeef21dbc5186/FormData.js#L4

Thanks for the quick reply :)

Digging deeper it seems like maybe there's something wrong with the minified version from NPM. If we take FormData.js and minify it ourselves, everything works. Is that possible?

The problem is essentially that at the point that it tries to access .Symbol the object is undefined.

if it fails at the point of .Symbol then i might suspect that it might have a problem accessing the global object

  var m = "function" == typeof Object.defineProperties ? Object.defineProperty : function(a, b, c) {
      a != Array.prototype && a != Object.prototype && (a[b] = c.value)
    },
    // failing?????
    n = "undefined" != typeof window && window === this ? this : "undefined" != typeof global && null != global ? global : this;

  function p() {
    p = function() {};
    n.Symbol || (n.Symbol = r)
  }

My colleague who actually has access to Edge is currently out of the office so I'll get him to check when he's back.
