On firefox 55.0.3 64bit, when I have enabled uBlock Origin or Adblock, I have strange initalization issue in version 2017.2.621

The below function from kendo.all.js is throwing exception: root is null.  This happens when addon is enabled even if site is whitelisted. I need to disable addon totally to make editor work. I can reproduce issue on Dojo or demo site. I believe previous version didn't have this issue.

function textOnly(root) {
                    var childrenCount = root.childNodes.length;
                    var textChild = childrenCount && root.firstChild.nodeType == 3;
                    return textChild && (childrenCount == 1 || childrenCount == 2 && dom.insignificant(root.lastChild));
                }

Hello Marcin,

I can confirm that this is a known issue in the Kendo UI Editor. The bug can be reproduced with different addons in the latest version of Firefox. You can find more information about the problem in this GitHub issue.

A fix is already implemented and will be available with the next release of Kendo UI, which is scheduled for mid September.
