Took me a while to understand, but the gist of the bug is:
“Show Original” button only applies to current “page” of posts, and it not respected when loading next page via scrolling
Right?
This would drill down to the route at GET https://meta.discourse.org/t/#{topic.id}/posts.json?post_ids[]=#{posts.id} not respecting the cookie content-localization-show-original: "true".
