Problem with scrolling and images load - https://anime-bit.ru/

Hello everyone! I have a slight issue with the website https://anime-bit.ru/ in Firefox on Android. When scrolling down the page, it doesn't load further, and images don't appear. It works fine in Firefox on desktop and in Chrome on Android. I'm not sure whether the problem is with the website or the browser. I’m attaching a video demonstration of the issue. Would appreciate your confirmation or any suggestions!
