it looks like all calendar events may be referenced when calculating the scroll offset for the event list as the result is farther past the current date than expected.

to repro:
- go to yui site but don't log in.
- go to YUI 3 calendar on site. (both YUI events and YUI project calendars are enabled by default)
- turn off the yui events calendar
- refresh the page

you will momentarily see all of the events draw then the events for the disabled calendar will be removed. however, the scroll position will be past the current date. possibly the scroll position is
calculated before the disabled events are removed. is it possible to not render the disabled events? seems like this is a new behavior and they had not previously been rendered.
