onAppointmentUpdating passes e.newData directly into conflict detection. In Scheduler, newData can be partial (only changed fields), so detectConflict() may receive an appointment without startDate/endDate/assigneeId and miss conflicts. Consider passing a merged object (e.g., old + new) here, consistent with the React/Vue/Angular versions of this demo.

Suggested change

	handleConflict(e, e.newData);
	const updatedAppointment = $.extend({}, e.appointmentData, e.newData);
	handleConflict(e, updatedAppointment);
