When the window is small enough that the scroll bar appears on the right, any
appointments that are adjacent to midnight are vertically misaligned, getting
better until the right-most event is where it is supposed to be.

It looks related to the bug 258051

Reproducible: Always

Steps to Reproduce:
1.Create an event; Set it to recur at least twice within the same week and to be
adjacent to midnight.
2.Go to the Week View
3.

Actual Results:  
The events prior the last occurance of the event of interest are all shifted
vertically.  This affects all events during the day as well; they are shifted
up, getting progressively worse as you go to the left.

Expected Results:  
The recurring event should have been displayed adjacent to midnight and all the
events during the day should line up with their respective times.

I found more specific details on how to reproduce the bug. 

Steps to Reproduce:
1. Create an event that ends at either 11:59pm to 12:00am and starts at 11:26pm
or later.
2. Set it to recur in any combination that puts it occuring more than once a week.
3. Go to the week view and resize the window to have a vertical scroll bar.

Also, I noticed that if you have a multiday event in the same week, or any event
that coincides with the misaligned event, the vertical misalignment is compounded.

Attachment: very bad case

This shows the bug in a very bad case scenario.  I assume it will get worse if
more events are added.

I have three events in this image:
-one repeating daily 11:45-11:55pm
-one repeating sunday through friday 11:58-12:00am (the event causing all the
trouble)
-one on tuesday at 8pm

Attachment: sample calendar: event at 19--20:00, repeated event at 23:30--23:45

Confirm: occurs only when vertical scrollbar is present.  Affects vertical
alignment of evening events as well, such as an event at 19:00--20:00.

This bug is fixed by patch to bug 243494, in particular by addition of
calendar.css style rules so .week-view-event-class has 
  overflow: hidden

since that patch is checked in, marking this bug fixed.
