pace.min.js is corrupting XMLHttpRequest.DONE value

[a2intl]

We had a customer that was using this plugin report a bug that our Consent Manager (Quantcast Choice) was not working. We tracked it down XMLHttpRequest.DONE no longer having a value of 4 due to an override done by extendNative at

https://github.com/dcooney/wordpress-ajax-load-more/blob/master/vendor/js/pace/pace.js#L444

The specific bug is on line

https://github.com/dcooney/wordpress-ajax-load-more/blob/master/vendor/js/pace/pace.js#L360

where key is not localized per loop iteration, so all the properties of the "extended-native" version of XMLHttpRequest end up retrieving the last-property-iterated.

I don't see a fix in the latest version of pace-js on github: https://github.com/HubSpot/pace/blob/master/pace.js , but I think you can fix this by replacing lines 359-361 with:

              get: (function(keyIn) { return function() {
                return from.prototype[keyIn];
              })(key),

It looks like this has been reported as CodeByZach/pace#261

I've submitted a fix CodeByZach/pace#504 which has been merged upstream, if you want to grab the new pace.js and pace.min.js files.
