/**
 * Hook to handle actions for a navigator, including state updates and bubbling.
 *
 * Bubbling an action is achieved in 2 ways:
 * 1. To bubble action to parent, we expose the action handler in context and then access the parent context
 * 2. To bubble action to child, child adds event listeners subscribing to actions from parent
 *
 * When the action handler handles as action, it returns `true`, otherwise `false`.
