Steps to reproduce

We got a recent microsoft security path release KB4040685 installed in my Windows 7 machine. After this installation none of the drop down click event is fired in our angular website that uses bootstrap 4.0.0.alpha.6 version.

I have created a Plnkr to demostrate this http://plnkr.co/edit/kdTqmnnCo0Y7j3GxzJSs?p=preview

Open the dropdown menu and click Say Hello. It shows nothing, but If I emulate to IE10 mode it works as expected.

After installing KB4040685 Refer SO.png image 1

Working in IE 10 mode Refer SO2.png image 2

I have tried to remove display:none from bootstrap css class dropdown-menu and seen click events are firing. But we dont want to see a menu until user click it.
