Calendar invitation in senders language

[rullzer]

1. Instance language is English
2. userA sets their language to German
3. userB sets their language to Dutch
4. userA has email [email protected]
5. userB has email [email protected]
6. userA creates an event with userB as participant.

In this case I would assume that userB receives the invitation email in Dutch. But the e-mail is in German.

I still get the invitations in German on our cloud 🤔
