Minor issue, but the invitees for a recurring event are listed in reverse alphabetical order:

Subsequent instances of the event do list the invitees in the correct order:

Steps to reproduce:

1. Create a recurring event and invite people.
2. See invitees listed in reverse alphabetical order.
3. Click Next to go to the next instance of the event. Invitees are not yet shown.
4. Click Previous and Next again.
5. Invitees are now listed in alphabetical order at this instance, but not at the original event.
