Description
This issue has been migrated from [#2065](https://github.com/matrix-org/synapse/issues/2065).
---
1. Be a guest user
1. Be invited to a room with guest access permitted from a different HS
Join request is 403ed.
This is because synapse does a check for whether guests are allowed before anything else (https://github.com/matrix-org/synapse/blob/474c9aadbe542440bb7cd764a654518b5c36f851/synapse/handlers/room_member.py#L246) and if the invite is from a remote server, it doesn't yet have the guest_access state.
