e-appointment width wrong calculation

I noticed that scheduler controller might calculate width for some columns wrong.


see this picture. All events are absolutely the same, but whereas for other the calculated value is 100px, for dat March 11th is super small 4px, what could be a reason for this? I suppose it might be something with wrong calculation related with February days count, as this view is weekly timeline view and duration 5 weeks. For other months there is no this issue. The scheduler starts from Sunday February 26th. Could you advise what's wrong?

Here is the code for the view:

                    <ScheduleView Option="View.TimelineWeek" DisplayName="Monthly" IsSelected="@true" Interval="5"  MaxEventsPerRow="50" AllowVirtualScrolling="@true">

                        <ScheduleViewTimeScale SlotCount="1" Interval="1440">
