XUL popups (i.e. FrameConstructionItem instances with mIsPopup==true) behave like out-of-flow content -- in particular, they generate nsPlaceholderFrame instances. So, they need the same placeholder-wrapping behavior that we have for other out-of-flow frames inside of an emulated legacy box, in order to satisfy our existing invariants.
