When using a CalDAV server (3rd party, not Apple), I cannot use "Remind me at a location" or event "Location" for calendar entries, these values are just lost when the entry is stored. Might be that the CalDAV Server dosen't support these non-standard attributes (yet I'm not sure the apps even try to store that as a custom attribute, which the server might allow), but even then I'd expect that the phone at least stores theses attributes locally (then they won't get synced - still better than GETTING LOST).

Steps to Reproduce:
1. Configure a non-Apple CalDAV Server
2. Add Reminder or calendar Event
3. Add a location

Expected Results:
The location is still there when editing end. If possible, is synced to CalDAV server (and thus do other devices as well - maybe as a custom attribute or encoded in some standard field that can be "abused" for that purpose), if not possible, it is at least remembered locally on the device (and the event w/o location is synced to server).

Actual Results:
The location is just lost, it's gone and all the location features are unusable.
