After update to beta 14.1 I've found an issue with scrolling up the topics. When you scroll using page up button it works ok, but if you scroll using mouse wheel or sliding on mobile Flarum loads 50 to 100 messages at once and put you at the top of those messages, so you need to scroll down to found the point of auto load.
And when you scroll down to the page end and then try to scroll up again then it scrolls ok, loading 10-20 messages at once and you stay at the right place after auto load.
Sorry for poor explanation, but I hope you understand what I wanted to say 🙂 Is it a known issue or it's me and my forum only?
