<ref>s displayed on a page (either board or topic), should always increment, and never duplicate each other. Otherwise we get duplicate #cite_note-1 links
E.g. If I click the ↑ for the "foo" reference at https://www.mediawiki.org/w/index.php?title=Topic:Sm9eagq43pa1pjxg&topic_showPostId=smiryzgo2387qfe2#flow-post-smiryzgo2387qfe2
Expected: it only scrolls up to "w:test banana [1]" directly above.
Actual: it scrolls to the top of the topic, to the "One list [1]", which is in the post above.
