/* Menus and popovers, and the Wayland rule that governs where they may be anchored.
 *
 * Wayland compositors only accept the top-most enclosing popup as a popup's parent. Anchoring
 * to the widget the user actually clicked -- which is what every naive call does -- produces a
 * popup placed at the wrong end of the screen, or none at all. Every popup in the application
 * goes through here so that rule is applied once. */
