What causes z-index to be ineffective with sticky elements?

In my website, I've implemented rollover effects in a sticky footer and a responsive menu that stays at the top. However, when the menu is opened and extends over the footer, it covers everything except the rollovers.

I've made numerous changes and even recreated a simplified version in jsfiddle where it worked. But those changes don't seem to work on my actual website...

Here is the working jsfiddle: /m_d_a/y7Lj3rms/26/

And here is the problematic jsfiddle: /m_d_a/4bLyt681/5/

I apologize for any formatting issues with the code tags. I understand that there's a lot of javascript involved, most of which comes from external plugin files that I'm not familiar with. So, I believe the issue lies within that code. Any help in resolving this would be greatly appreciated. I'll also update the title of this question once a solution is found to assist others facing similar problems in the future.

Thank you.
