Describe the bug

Consider the following code sample:

[Fact(DisplayName = "DeadLetterLoggingSpecs: Should log the underlying message, not the IWithTrace wrapper")]
public async Task ShouldLogTheUnderlyingMessage()
{
    // create a new SuspendableActor
    var actor = Sys.ActorOf(Props.Create<SuspendableActor>());
    Watch(actor);

    await EventFilter.DeadLetter<string>().And.DeadLetter<double>().ExpectAsync(2, () =>
    {
        // suspend the actor (via a blocking Task)
        actor.Tell(new SuspendableActor.Suspend());

        using (var newOp = Tracer.StartActiveSpan("startOp"))
        {
            // queue up dead letters (should be descendants of the current span)
            // this should force these messages to be wrapped inside a SpanEnvelope
            actor.Tell("hi");
            actor.Tell(1);
        }
        
        // sends a system message that will cause the actor to shutdown regardless of its mailbox state
        Sys.Stop(actor);
        
        // wait for the actor to shut down
        ExpectTerminated(actor);
    });

}

The DeadLetters that should be received should be of type string, int, but the assertion checked for string, bool.

Worth noting: if I change the expected type on the first assertion away from string to something like SuspendableActor this assertion will fail.

Expected behavior

The EventFilter assertions should type check everything in a composed assertion.

Actual behavior

Only the first message in the EventFilter expression appears to be properly type-checked.
