Bug description

Frequently getting a message in the server log:

Validation error in iCalendar: TRIGGER MUST appear exactly once in a VALARM component

But as far as I can tell, the calendar entry that it's reporting about conforms to the validation requirement:

BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
PRODID:-//Sabre//Sabre VObject 4.5.4//EN
BEGIN:VEVENT
UID:f9b5b6ca42cf624b1c11bff4d206a686
DTSTART:20240416T120000
DTEND:20240416T130000
SUMMARY:[redacted]
DESCRIPTION:[redacted]
CREATED:20240411T134539Z
DTSTAMP:20240411T134539Z
BEGIN:VALARM
ACTION:DISPLAY
DESCRIPTION:[redacted]
TRIGGER;RELATED=START:-PT15M
END:VALARM
BEGIN:VALARM
ACTION:DISPLAY
DESCRIPTION:[redacted]
TRIGGER;RELATED=START:-PT1D
END:VALARM
END:VEVENT
END:VCALENDAR

That looks to me like TRIGGER is only appearing exactly once in each of those VALARM components.

Steps to reproduce

Not entirely clear. Just create a calendar event with the same structure as above I suppose.

Expected behavior

Should not emit invalid warnings.
