Steps to reproduce:

actually when i can add progress to an ajax upload request with EventListener , but the returned value is not right.


Actual results:

for example i got the following code 
xhr.upload.addEventListener('progress', function(event) {
						console.log(event);
                        var percent = 0;
                        var position = event.loaded || event.position;
                        var total = event.total;
                        if (event.lengthComputable) {
                            percent = Math.ceil(position / total * 100);
                        }
                        options.uploadProgress(event, position, total, percent);
                    }, false);

but event.loaded gives the same value every time , till the upload finishes ... as soon as it finishes it gives all the filesize as the loaded once.


Expected results:

each time it runs it should give the correct value of event.loaded as it was in previous versions
