When retrieving paginated tasks with before_parent query string, some relays might not be returned

[duckbytes]

In api/task/task.py line 368 tasks are filtered by before parent int ID and then paginated. This means during the infinite scroll on the dashboard can skip jobs if they are split by a relay.

A workaround is on the front end to make a request that uses before_parent - 1, but this means the 404 return is never triggered when there are no tasks left to return
