rrule.after method doesn't work if there is a TZID in the dtstart

[Remmelt13]

Reporting an issue

The new version >2.7.2 breaks the after method if the rrule string includes a tzid. timezone on the machine is CET. It is also happening on the demo app setting tzid breaks the output of rrule.all()

Code:
const date = new Date() const rrule = "DTSTART;TZID=Europe/Berlin:20231120T110012\nRRULE:FREQ=DAILY;INTERVAL=1" const tempRule = rrulestr(rrule); const nextOccurrence = tempRule.after(date, true)
