Steps to reproduce
1) Open the scheduler demo at alloy-ui/demos/scheduler/index.html
2) Create an event on each three consecutive days from 23:30 (11:30PM) till 00:30 (12:30AM). The first half of the event is at the end of the first day, and the second half of the event is at the beginning of the next day.
Result: the blue bends representing the event occurrences at the bottom (end of the days) seem to be faulty. They are not as long as the length of a column. The bend at the top, all have the full length of the columns.
