dispatchOwnPropertyChange(key, value, beforeChange?)

Informs property change listeners that the value for a property name has changed.

This method is particularly useful for cases where there is a computed property, defined by a getter, that can change behind the scenes, without assigning to the property itself. Such types must manually dispatch the property change at the point the computed property changes.
