Demo fiddle not working in IE 11

[deltadada]

I don't believe your fiddle is working in IE 11 -- http://jsfiddle.net/thorst/2aGL4/
It loads as 'active' and never changes.

I'm using IE Browser Version 11.850.15063.0
In my implementation with IE 11 and jquery 3.3.1 on Windows 10, the mouse wheel does not work and users can't input into textareas or use dropdown select when idleTimer is instantiated on $(document)
