Description
This issue has been migrated from [#15263](https://github.com/matrix-org/synapse/issues/15263).

*Sister issue to `/context` backfilling events: https://github.com/matrix-org/synapse/issues/3848*
---
The client `/event` endpoint does not try to backfill unknown events from federation. "This means that if I try to follow a permalink for a room and my server doesn't have that event locally, the permalink fails. This is pretty awful UX."
