Transparent calendar still triggers Talk "In a meeting" status

Steps to reproduce

Description

I imported an .ics calendar into Nextcloud Calendar and configured the whole calendar as transparent using:

Calendar settings → Never show me as busy (set this calendar to transparent)

However, whenever an event from this calendar is currently taking place, Nextcloud Talk automatically changes my status to:

Busy – In a meeting

This happens even though the calendar should explicitly not affect my availability.

Additionally, the imported events themselves already contain:

TRANSP:TRANSPARENT

So both the calendar-level setting and the individual event data indicate that these events should be treated as transparent.

Steps to reproduce

1. Import an .ics calendar into Nextcloud Calendar.
2. Open the calendar properties.
3. Enable:
   Never show me as busy (set this calendar to transparent)
4. Save the calendar settings.
5. Wait until one of the events in this calendar is currently taking place.
6. Open Nextcloud Talk and check the user status.

Expected behavior

Expected behavior

Events belonging to a calendar configured as transparent should not mark the user as busy.

They should therefore also not trigger the automatic Talk status:

In a meeting

This should especially be the case when the individual event itself also contains:

TRANSP:TRANSPARENT

Actual behavior

Actual behavior

During an event from this transparent calendar, Nextcloud Talk automatically sets the user status to:

Busy – In a meeting

It appears that the mechanism used for the Talk automatic meeting status does not respect the Calendar transparency setting and/or the event's TRANSP:TRANSPARENT property.

Additional info

No response

No source file, test, or entry point is named in the report. Start by tracing the automatic Talk “In a meeting” status handling and how it reads calendar and event transparency, then reproduce with the imported .ics calendar. Done means transparent calendars and events with TRANSP:TRANSPARENT no longer set the automatic meeting status, with coverage for both settings.
