 // |customHandler| allows a handler function to be called each time an extension
 //     event is caught by its event listener. The DOM event should be dispatched
 //     within this handler function. With no handler function, the DOM event
 //     will be dispatched by default each time the extension event is caught.
 // |cancelable| (default: false) specifies whether the event's default
 //     behavior can be canceled. If the default action associated with the event
 //     is prevented, then its dispatch function will return false in its event
 //     handler. The event must have a custom handler for this to be meaningful.
