Steps to reproduce the behavior

1. Use Project Tasks Template and go to Calendar View
2. On either a Saturday or Sunday, create 8 to 10 tasks
3. Click on +x more button below the tasks
4. Observe: Expanded task list displays over originally created tasks and the +x more button (see screenshot 1). The expanded task list on Monday - Friday displays properly (see screenshot 2)
5. With the expanded task list still open, use either the vertical or horizontal scroll bar to scroll
6. Observe: The expanded task list closes

Expected behavior

For 4) - display the expanded task list as it displays on Monday - Friday For 6) - I would expect the expanded task list to stay open when I scroll vertically or horizontally
