The ban -> unban -> invite appears to be fine, but as soon as the invitee accepts the invite to the room, their join soft fails, and they remain in an invited state. It appears as if continuwuity is prioritising the leave membership caused by the unban action over the invite one when checking the join against current state.

State res trace logs attached. issue is not federation exclusive, the state does not resolve correctly on the origin server either.
