All of them? Firefox 137 on macOS Intel

After watching it sit there for 5-10 seconds before loading the section 'data-framer-name="Join"' I decided to inspect the element after it did load to see what it was doing. That's when I spotted all the JS and data attributes implying it was likely built with one of those drag-and-drop site builders, which explains why it may be behaving in an unexpected way for you. It also explains why it may default to "fade in on scroll" behavior, if my experience is any indication, because marketing folks _love_ that shit

That's so weird – I can't repro at all! I'll keep digging.. If anyone else reading this is also experiencing this, please shout!
