Feed pager: pictures (and clips) in a quoted post are in it too. Adam full-screened the screenshots in a quoted post and couldn't swipe on: a tap on a picture in the feed opens the pager on it only if it is among the pager's slides, and those were each feed post's own pictures — a quoted post's are its own, drawn inside the one quoting it, so the tap fell back to the picture alone (the lightbox), with nothing to swipe to. Now the pager takes, after each post's own pictures (or clips), those of the posts it quotes, as far as they've been fetched (and not hidden or folded as sensitive): swipes walk through them and on to the next post's, the slide's details name the quoted post's author and words, and closing lands on the post that quoted it. tools/quote-pager-test.js (a post with its own picture quoting one with two, served only by a relay: the tap opens the pager on the quoted picture, down through the quote and on, up to the quoting post's own, the quoted author in the details, Escape onto the quoting post) — with the quotes left out it fails as Adam saw, the picture opening alone.
