I am trying to use card flipping as part of an animation, and I am following the cool-looking example in the GSAP codepen. However, I noticed that it does not work on IE 10. On IE 10, the cards do flip, but instead of seeing the "back" card you see the backface of the front card. It appears as though there is a problem with the backface-visibility in IE 10. What can I do to make this also work in IE 10? Thanks!
