Most recently edited tab is duplicated on the "recently added" list

this tab, as of December 12th, 2021 @ 11:38 PM EST, is the tab that has been edited most recently. as a result, all the previous edits to that tab show up as their own individual edits, clogging up the recently added page with plenty of erroneous duplicates.

this only happens with the most recent tab; tabs that have been recently edited more than once (but not most recently) do not have this issue.
