CSS Transform Obliterates Position: Fixed

Apparently, if you have an element with a CSS transform applied to it, and try to put an element inside of it with position: fixed;, that element acts like an element with position: absolute; instead of fixed.

See the Pen transform's effect on position: fixed by Cameron Spear (@CWSpear) on CodePen

This only took me like an hour to figure out...

Hope I can save someone the trouble!
