Canceled appointments disappear from calendar
Sometimes appointments (ews invitations) are canceled by the inviting person or by myself.
The appointment is deleted from the calendar after confirming the cancellation.
It does not make a difference if Edit|Preferences|Calendar and Tasks|Display tab|Hide canceled appointments is set or not.
Steps to reproduce: 1a) Confirm a cancellation (received by mail) by pressing "refresh" -> "Changes in the calendar will be saved. Please wait ..." 2a) Cancellation confirmed by: "Entered in calendar ":Calendar" as Canceled" OR 1b) Call off an invitation by yourself by deleting the event 2b) Trigger this way a cancellation on the side of the invited persons
Expected behavior: If Edit|Preferences|Calendar and Tasks|Display tab|Hide canceled appointments is set to false, the appointment is still visible in calendar, but has a "Canceled" Prefix and a strikeout font.
Actual behavior: The calendar events is deleted and thus disappears from calendar.
