Steps to Reproduce

Create 2 CalendarItems in the same day, with the end of the first one being a full hour, and the start of the next one being the same full hour.

ex: test1 [14:00, 16:00]; test2 [16:00, 18:00]

Current Result

2nd event will display as if it was overlapping the first event (50% size, packed to right side)

Expected Result

If the 2 events are not overlapped, they should use the whole column.

Debug Information

FixPosition function checks for timeslots occupied by events.

events that end exact boundary of a time slot are marked as occupying the timeslot.
