I got a reply to a comment in what’s become quite a bit post (≈150 comments). Clicking the message in the inbox goes to the post comments but not to the reply. It seems to go to a slightly different place each time I open it.
I saved the original comment I’d replied to, and navigating from my ‘saved comments’ does go to the right place.
I believe I have this fixed now. This issue has to do with loading media and link previews above the destination comment. When the previews are loaded, the destination scroll position is changed. I’ve updated this to adjust the scroll position when previews are loaded, and it seems to be working in my tests.
