v4.3.2

When using async transport, UnrecoverableMessageHandlingException business logic does not work at this moment at all.
Symfony\Component\Messenger\Middleware\HandleMessageMiddleware:82 wraps all \Throwable (not only UnrecoverableExceptionInterface exceptions) occurred in handlers in Symfony\Component\Messenger\Exception\HandlerFailedException, when Symfony\Component\Messenger\Worker:194 wants only UnrecoverableExceptionInterface.
At this moment the only possible solution to prevent retrying is disable totally retrying strategy.

To reproduce, just throw UnrecoverableExceptionInterface in any kind of async handlers (i did not test on sync handlers, but think that situation is the same).

As a solution, it's be better to check payload of HandlerFailedException in Worker.
