PopupWidget needs to have its body positioned absolutely and anchor relatively to it, and not vice versa. Doing it the way we do now causes problems with measuring elements and scrolling them into view (bug 71540). However, we currently depend on positioning popups that are used as part of other widgets with just CSS, which probably won't work with this.
