Description

Working fine on current 6.2 branch.

I define an event listener like this:

$services
        ->set(MessageEventListener::class)
        ->tag('kernel.event_listener', ['event' => MessageEvent::class])
        ->args(
            [
                '%env(MAILER_EMAIL)%',
            ]
        );

However the handler is no longer being called.

How to reproduce

I'm trying to work out why the AbstractTransport::send method does not appear to be called anymore and why the MessageEvent event listener would not be fired.
