?before= on mixed user history will ocassionally return incorrect submission history
clicking the "Prev" button on the user history page will occasionally return a list topped by thread submissions which should, chronologically not appear on that page. Examples: Clicking "next" from the profile will lead to the following URL: https://tildes.net/user/clerical_terrors?after=c-2gjt The page looks like this to me (warning, very large image) https://i.imgur.com/qrd5Edg.png No problems noted, clicking "Prev" returns to the normal user page, clicking "Next" again generates another normal page (https://tildes.net/user/clerical_terrors?after=t-94h) Clicking "Prev" from ?after=t-94h (to https://tildes.net/user/clerical_terrors?before=c-2cdy) however generates a timeline which has many submissions on top, in chronological order, but out of order with the comments below: https://i.imgur.com/k1y59NW.png Clicking "Next" two more times from this position, to [...]?after=t-8t0 then clicking "Prev" again to ?before=c-2adz generates a longer version of the same list: https://i.imgur.com/tb0cEUG.png
