To add to the above, if I remove or comment out ScrollTrigger then "#scroll-section-1" will never be cut off since it has the minimum height set, even when the viewport is set much smaller, it's only when I add in pinning that the height of "#scroll-section-1" doesn't honor the min-height set. I would assume this is due to it being set to fixed or maybe the min-height is being overridden by the viewport height?
