    * `IronResizableBehavior` is a behavior that can be used in Polymer elements to
    * coordinate the flow of resize events between "resizers" (elements that control the
    * size or hidden state of their children) and "resizables" (elements that need to be
    * notified when they are resized or un-hidden by their parents in order to take
    * action on their new measurements).
    * Elements that perform measurement should add the `IronResizableBehavior` behavior to
    * their element definition and listen for the `iron-resize` event on themselves.
    * This event will be fired when they become showing after having been hidden,
    * when they are resized explicitly by another resizable, or when the window has been
