Fixed Background Image not working in Chrome on the live site

Hey Webflowers,

the fixed background image property only seems to be working in the designer but not on the live site. I’ve also added it via CSS incase Webflow has some issues but that didn’t help the problem either.
css-selector { background-attachment: fixed; }

Here’s the live site: Projects

Here’s a loom to demo the issue: Loom | Free Screen & Video Recording Software

Appreciate any advice on this!
