I am new to gsap so I apologise in advance if I am missing something obvious.
I've created a sandbox of the issue im having where the element I am trying to pin is not pinning to the top of the viewport when scrolling down the page, the link is here: https://codesandbox.io/s/rough-moon-x34wgz?file=/src/App.js .
Any help or advice would be massively appreciated!
