Indeed. Sorry I'm at work at the moment. Also toggleActions doesn't seem to work animation plays without reversing.
let tl = gsap.timeline({
// yes, we can add it to an entire timeline!
scrollTrigger: {
start: 0, // when the top of the trigger hits the top of the viewport
end: "+=500", // end after scrolling 500px beyond the start
toggleActions: "restart pause reverse pause",
}
});
