Win 7 + IE 11 Codepen not working

Hello,

I create pen on codepen. But when I checked it in IE, that IE doesn't work well with codepen. I tried different pens of other people in IE and it failed everytime.

Here is the pen: https://codepen.io/reginna/pen/KBBvZq

I already read the similar problem: Win 8, Win 8.1 + IE 11 Fixed Positioning Bug? (https://social.msdn.microsoft.com/Forums/ie/en-US/9768ecd5-c48e-49a4-9609-894d8a62bd61/win-8-win-81-ie-11-fixed-positioning-bug). And added codepen to trusted sites list, but there was useless.

Here is F12 > Console tab error messages:
