IE11 + 4.1: JavaScript runtime error: Object.keys: argument is not an Object

[Alessandro3325]

After upgrading my project to bootstrap 4.1 I get a JavaScript runtime error: Object.keys: argument is not an Object in Internet Explorer 11.

This can be simply reproduced by opening http://getbootstrap.com/ in IE 11!
