Does not attach to form-type-managed-file

Thanks for the module.

I needed to do this:

--- a/js/upload_progress.js
+++ b/js/upload_progress.js
@@ -6,7 +6,7 @@
 Drupal.behaviors.upload_progress = {
   attach: function (context, settings) {
 
-    jQuery("input[type=submit]", ".file-widget, .image-widget").each(function(el) {
+    jQuery("input[type=submit]", ".file-widget, .image-widget, .form-type-managed-file").each(function(el) {
       var ajax = Drupal.ajax[this.id];
       ajax.progress.url = undefined;
       ajax.options.uploadProgress = function(event, partial, total, percentage) {

To get it to attach to my custom managed file upload fields. Any reason why it shouldn't include this?
