#380

Thanks for the fix. The "content doesn't fill the viewport on initial load" problem is real, and worth acknowledging. The v7.0.0 rewrite handles this naturally through the IntersectionObserver sentinel: as long as the sentinel div remains visible in the viewport, next() keeps getting triggered, so the manual post-load height check is no longer needed. Closing as superseded.
