*
* Due to the nature of history management, no callbacks are allowed.
* Use the 'beforestatechange' and 'afterstatechange' events instead,
* or overwrite the beforeLoad() and afterLoad() methods on the
* DOM element you're loading the new content into.
* Although you can pass data into pushState(), it shouldn't contain
* DOM elements or callback closures.
*
* The passed URL should allow reconstructing important interface state
* without additional parameters, in the following use cases:
* - Explicit loading through History.pushState()
* - Implicit loading through browser navigation event triggered by the user (forward or back)
* - Full window refresh without ajax
* For example, a ModelAdmin search event should contain the search terms
* as URL parameters, and the result display should automatically appear
* if the URL is loaded without ajax.
*
* Alternatively, you can load new content via $('.cms-content').loadForm(<url>).
* In this case, the action won't be recorded in the browser history.
