SearchKit: Join on contact reference in event not working if event isn't root entity
I'm trying to create a SearchKit for participants. I have a join on the participant's events as a secondary entity. From the events I then want to join on a contact via a custom field on the event that is a contact reference - but it doesn't work.
When I have the event as the root entity everything works fine. Yet, if I start from participants I can't join on the contact reference.
