I have to give you credit for going this far into proving whatever we're trying to prove. However, who the hell in the real world infinite scroll this much? Some people do things that would make any QA team more valuable, and you're starting to sound like someone I'd love to have on any QA team I'd work along side.

This really sounds like one of those issues a dedicated person finds where the devs look at it and say no reasonable user would ever do this. The issue if not closed as "won't fix" gets deprioritized so low that it never gets looked at again. Even as a dev, I'd not have the patience to recreate the problem. It's just such an outside edge case from expected behavior/usage that I don't even know what to say in response.
