### I found four options:

* Use `ReflectionProperty` to get the priority parameter of a listener from `EventDispatcher`
* Get the priority parameter of a listener from `\Symfony\Component\HttpKernel\Debug\TraceableEventDispatcher::addListener`
* Do not wrap a `EventDispatcherInterface`, reimplement one.
* Do not wrap a `EventDispatcherInterface`, extend one to access the priority parameter of a listener .
* Add PriorityAwareEventDispatcherInterface on EventDispatcher.

### This PR try first option.
