CKEditor does not work on IE11

[Bruno]

Open ​http://ckeditor.com/features with IE 11 or Edge in IE 11 emulation

Unable to get property '1' of undefined or null reference (16, 157)

navigator detection fails detecting ie 11 because rv: test is not done prior to edge regex test

To solve issue : sorry (dont have the source proper variable names) var a=navigator.userAgent.toLowerCase();

if(/rv:([\d\.]+)/.test(a)) {

var d=a.match(/rv:([\d\.]+)/);

} else {

var d=a.match(/edge[ \/](\d+.?\d*)/);

}

I had just checked IE11 and Edge in IE11 mode - everything is working perfectly.
