// Specifically that if a room's history visibility before or after a particular history visibility event
// allows them to see events (a boundary), then the history visibility event itself should be shown
// ( spec: https://spec.matrix.org/v1.8/client-server-api/#server-behaviour-5 )

// This also aims to emulate "Only see history_visibility changes on bounadries" in sytest/tests/30rooms/30history-visibility.pl
