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

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.

    For troubleshooting, please uninstall the update and confirm the expected behavior has been restored. Next, please reinstall the update KB4040685
    and confirm the expected behavior has been lost.
