Please see my attached video for details:
When the webpage is loaded and cached, as when the screen capture started, the lazyloading is not a problem, even when the connection is slow, while scrolling down, lazyloading is not a problem.
The problem occurs on scrolling up even with a good connection, even when the website is loaded and cached.
As you can see, it takes up to a SECOND until the feed comes into view and this is what's annoying and degrades the experience.
I only noticed this while scrolling through the feed - post scrolling isn't a problem.
