document.documentMode return undefined

Hi

I was testing a little around, and hard to come up with some tests for this, but in some cases document.documentMode are returned undefined when identifying IE.

Mostly I encountered this on ES6 transpillers where they don't have a window object directly. Example es6transpiller() where you have to add globals like / globals window, document / if you need access to window.

There are also several other scenarios this happen. Simply because the console (F12) are not open.

As a workaround I found this solution:

var jscriptVersion = window.ScriptEngineMajorVersion,
ie = jscriptVersion && jscriptVersion();

With this code it works in all scenarios.

@marcorra I'm confused how your write-up is related to AngularJS.... Closing as it doesn't sound like a bug report / feature request for AngularJS....

@pkozlowski-opensource If you are confused take a look at this source code line from inside AngularJS

https://github.com/angular/angular.js/blob/master/src/Angular.js#L189

Here you clearly see that AngularJS are using document.documentMode to identify IE.

This issue ticket was only to mention that this is will not identify IE in some use cases, as the intension is inside AngularJS.

Hope that was clear, and you are not confused now.
