DropDownCalendarControl and HTTPS causes security warning

Hi,
I see that if I'm using DropDownCalendarControl with HTTPS, that cases security warning because of using iframes with empty src. (I see a similar post but with using menu, but is from 2006; isn't that issue fixed yet?)

How can I fix that?

Thank you.
