EXDATE not properly respected (floating EXDATE)

JD145 commented 4 years ago

I have a event series and deleted a single event with Thunderbird (synced via caldav). The deleted event still appears in the web interface (of course reloaded multiple times after deletion), but on Android (DAVx5 used) the single event is deleted correctly. Is it possible that there is a bug in web interface?

Steps to reproduce

Import the attached issue.ics (provided by an university)
Delete a single event using Thunderbird

Expected behaviour The deleted event should also dissappear in the web interface.

Actual behaviour The deleted event will be shown. In Thunderbird and Android Calendar App dissapear the event.

There is a duplicate EXDATE for that day, That might be causing issues:

EXDATE:20200106T095000
EXDATE:20191230T095000
EXDATE:20191223T095000
EXDATE:20200106T085000Z

Still able to reproduce on 2.0.0 beta1. Possibly upstream related.
