Not at the moment - it used to work that way, but I got feedback that users didn't want two different ways of accessing the favorites (a dropdown and a popup window). So I removed the dropdown that would disappear after clicking away and there is now only the popup that stays up. You can toggle the layout of the favorites window though (the icon at the top left) to make it a single vertical or horizontal line of icons. It takes up less space that way.
