popover events in dropdowns

[xero]

• popovers work fine for inline calendars.
• popovers nested in dropdowns will spawn the popover and close the calendar.

using the e.stopPropagation(); method (see) works great for downdown nested calendars, but breaks functionality for inline ones.

need to find the best way to determine if the calender is nested in a dropdown. this should be seamless to users, not a property set at initialization time.
