I'm having trouble getting the new Scroll Trigger plugin working in IE11. I can recreate the issue in a codepen. I provided the default URL, but to see the issue properly,  you'll need to look at debug view as that's the only view that works properly with IE11.   https://cdpn.io/DDI-Web-Team/debug/ef47361ba478799899683f07f3aaf0ae   If you look at the console in IE11 it says   Invalid property scrollTrigger set to .logo Missing plugin? gsap.registerPlugin()
