The continue params we are generating are for the first _extra_ notification that we don't display. In our 'continue' DB query, instead of re-retrieving this as our first notification for the next set, we are retrieving all the notifications after it. Thus that one notification always gets skipped.
Should be fixed by https://gerrit.wikimedia.org/r/#/c/82442/
