For example, for midnight shift start at 12am, an event start time 2020-09-16 10:30 PM to 2020-09-17 02:30 AM,
it is displayed as a whole day event stacked at the header of the Day/Week grid instead of showing continuous time slots from 10:30 PM on 16/09 to 02:30 AM on 17/09 that cross the midnight.
The example of 'https://bryntum.com/products/calendar/examples/shifted/' does not apply here because we have other events that are always cross the midnight. We want all events are displayed nicely in the time slot grid.
