AUI: problem with providing events in month view

The Liferay calendar portlet uses the AUI scheduler. I got the following problem:

I created the following two events on the same day that starts on the weekend (Sunday) and ends the next day (Monday) (the first day of the next week).

Event-A: start time: 12:10, Sunday end: 23:59, Monday

Event-B: start time: 12:00, Sunday end: 23:59, Monday

Ideally, both events should take place on Sunday and Monday. But in the planner (month) look at it, Event-A only covers Mondays and Events-B only covers Sunday and Monday, which is the correct rendering.

Anyone have an idea on this?

I have created a sample script that will be helpful for understanding this: http://jsfiddle.net/RU5xw/41/

YUI().use(
    'aui-scheduler',

function (Y) {
    var events = [{
        content: 'Event A',
        endDate: new Date(2013, 1, 17, 4),
        reminder: false,
        startDate: new Date(2013, 1, 16, 13)
    }, {
        content: 'Event B',
        endDate: new Date(2013, 1, 17, 4),
        reminder: false,
        startDate: new Date(2013, 1, 16, 12)
    }];

    var agendaView = new Y.SchedulerAgendaView();
    var dayView = new Y.SchedulerDayView();
    var eventRecorder = new Y.SchedulerEventRecorder();
    var monthView = new Y.SchedulerMonthView();
    var weekView = new Y.SchedulerWeekView();

    new Y.Scheduler({
        activeView: monthView,
        boundingBox: '#myScheduler',
        date: new Date(2013, 1, 4),
        eventRecorder: eventRecorder,
        items: events,
        render: true,
        views: [dayView, weekView, monthView, agendaView]
    });
});
