treeGrid.findCell not working in IE 11

As in subject line, the findCell isn’t returning a result in IE 11. Works fine in Chrome. Using IE 11.0.9600.18449 update version 11.0.35 (KB3185319)

Unfortunately the problem cannot be reproduced locally.
Could you pleas,e provide with a complete demo or share wit ha demo link, where the problem can be reconstructed.
Here you can find a tutorial about creating a complete demo:

I am surprised you cannot reproduce the problem locally. Here is the root cause of the issue.

I compiled a debug version of dhtmlx.js (dhtmlx_debug.js) and found the problem at line 626 of dhtmlx_debug.js, here indicated as line 627:

624		xmltop: function (tagname, xhr, obj) {
625			if (typeof xhr.status == "undefined" || xhr.status < 400) {
626				xml = (!null) ? dhx4.ajax.parse(xhr.responseText || xhr) : (xhr.responseXML || xhr);
627				//xml = (!xhr.responseXML) ? dhx4.ajax.parse(xhr.responseText || xhr) : (xhr.responseXML || xhr);
628				if (xml && xml.documentElement !== null) {
629					try {
630						if (!xml.getElementsByTagName("parsererror").length)
631							return xml.getElementsByTagName(tagname)[0];
632					} catch (e) {}
633				}
634			}
635			if (obj !== -1)	dhx4.callEvent("onLoadXMLError", ["Incorrect XML", arguments[1], obj]);
636			return document.createElement("DIV");
637		},

In Chrome (!xhr.responseXML) “xhr.responseXML” is null, which therefore calls “dhx4.ajax.parse(xhr.responseText”
In IE (!xhr.responseXML) “xhr.responseXML” is an object, which does not call “dhx4.ajax.parse(xhr.responseText” and fails to parse the XML.

Another possible cause: I am using “FETCH” in Chrome. for IE I used the FETCH polyfill. Perhaps that is the cause?
