Can't create event with comma in caldav calendar
Trying to create a calendar event in a CalDav calendar that contains a comma (,) in the title does not work. There's no error message, and afaict nothing is written to the debug log. Nothing happens at all.
Trying the same in the channel calendar created the event as expected.
I'm at Hubzilla 4.6 (commit 6f93d984) running on FreeBSD 12.1 with postgresql 9.6.16.
