[EventDispatcher] LegacyEventDispatcherProxy incompatible with WrappedListener #31457
Description
Symfony version(s) affected: 4.3.0
Description
The \Symfony\Component\EventDispatcher\LegacyEventDispatcherProxy implements the EventDispatcherInterface from the Contracts Bundle, but the \Symfony\Component\EventDispatcher\Debug\WrappedListener expects the EventDispatcherInterface from the EventDispatcher Bundle in its __invoke() method.
This leads to the error below.
How to reporduce*
Dispatch an Event with the deprecated dispatch(Event $event) signature, when your are in a dev env.
Possible Solution
The \Symfony\Component\EventDispatcher\LegacyEventDispatcherProxy should probably implement the EventDispatcherInterface from the EventDispatcher Bundle as it already implements all additional functions described by the EventDispatcherInterface from the EventDispatcher Bundle compared to the interface from the Contracts Bundle.
