On mobile, we have a ‘Back to Top’ bar at the bottom that has a high z-index so shows up in front of the cookie notice. I tried targeting a few different divs where the Cookie Notice is but couldn’t get this to update properly. How can I increase the z-index of the Cookie Notice div? Which CSS do I need to target and can I add that to my site CSS file? Our dev site is here: https://dev-lgam.pantheonsite.io/
