A common design pattern when building Web Applications is to use a UX Component with a Panel Navigator and child Panel Cards as the main controller for your application. Each of the Panel Cards might contain an embedded component. The embedded components are typically set to delay render till visible so as not to slow down the loading of the main controller UX. However, when the user gives focus to one of the Panel Cards, which causes the embedded component to load, you might want the embedded component to load instantly. This is now easily done by pre-loading the embedded components when the main controller component is loaded.
