«Mark as read when scrolled» issue after refresh

[TopoR]

Hi!
Thanks for the app! It's almost perfect for me except issue when after refreshing page (with auto-hide on refresh or even if you hide via button without refresh) it starts to mark as read only after some content load on this page and only from that point, leaving previous posts "unmarkable" from that point (they can be marked correctly, but only if I unload and load app again, until the next refresh).
Subjectively, it not marks content that already preloaded before hiding currently marked posts.

Some observations. It works correctly when I switch subreddit/page instead of refreshing current (different loading rings, after colored loading ring all content will be marked from the first post).
