Sorry, this issue just doesn’t seem to die. Updated to trunk today (b1f9ebe), and started experiencing the Infscroll disabled problem.
Experienced on Firefox 64.0.2, if that’s any help. Apologies if the code block doesn’t format correctly at first, I’m trying to sort it out.
Edit: Fuck it, the line breaks are there but aren’t being recognized. I can try to get a cleaner sample of whatever’s going on if it helps, just let me know.
Edit 2: It had crossed my mind that this might be a desync between entries being marked as read, new entries being pulled, etc, so I ran through my feed with the console open and filtering for “infscroll.” On the 15th append it finally duplicated, but the browser was also significantly slower, trying to handle TT-RSS and displaying the console at the same time. Duplication happened around 9:50 PM, with the feed marked as last updated at 9:09 PM.
