Subject: [PATCH] Fix the interface incompatibility of EventDispatchers

The `LegacyEventDispatcherProxy` now implements the full
`EventDispatcherInterface` from the `EventDispatcherBundle`.
Before it just implemented the Interface from the `Contracts` Bundle,
that made it incompatible with the `WrappedListener`.
This fixes #31457.
