IE11 aborts upload after 30s

IE11 aborts the ajax file upload always after 30s.

Trying to analyze this I found out that IE also does not like following syntax:

946                     xhr.ontimeout = (() => { 
947                         alert('Error: Server Timeout'); 
948                     }); 

Researching for the upload issue with IE11 I came across a post which mentioned that it helps to add a empty function for in progress. So I changed the code as followed, which does no more throw a syntax error and also solves the IE file upload:

946                     }).on("progress", function () {
947                     }).on("timeout", function () {
948                        alert('Error: Server Timeout');

As I am no developer, I have no idea if I am doing it correct, but this seems to fix the Problems with IE and does also not lead to problems with other browsers.
