Description

This just started recently, probably after an update to either Edge or Windows 10.

The uploadProgress function is not triggering until the upload is complete. It works fine in Chrome, Firefox and Internet Explorer. I've just downloaded the latest version of jquery.form.js and the issue is the same.

            uploadProgress: function (event, position, total, percentComplete) {
                if (running === false) {
                    running = true;
                    parent.postMessage("status|running","*");
                }
                var percentValue = percentComplete + '%';
                bar.width(percentValue);
                bar.html(percentValue);
            },

Research direction
Investigate the uploadProgress function in jquery.form.js, specifically the XHR upload event handling. Check if there's a known workaround for Edge. Look at comments in issue for any suggested fixes. Consider if it's an Edge specific issue with the progress event or a jQuery form plugin bug. Also check if the issue has been resolved in newer releases.
