Bug: opacity is ignored in IE8 when 'x' property is present

CodePen (I don't think this site supports IE8, so this may not be useful): 

See the Pen kxhfD by anon (@anon) on CodePen

 

Problem

Opacity isn't animated when there is an x-translation in Internet Explorer 8.

 

Code

// no opacity animation in IE8, works in modern browsers

var element = document.getElementById('box');
var animation = {
  x: -50,
  opacity: 0
};

TweenMax.from(element, 1, animation);

a

Extra note

If you replace the x with marginLeft, the opacity correctly animates.

Hmm...I just tested your code and it worked great for me in IE8 with the latest version of GSAP. Maybe you're using an old version? And are you using the "real" IE8 or some emulator? Emulators are known for rendering things wrong

Thanks for the prompt reply!  I was in fact using IE's debug tools to put it into IE8 mode, so I'll bet that's what it was.  Sorry to make waves over nothing!
