I had the same issue. I managed to resolve it by registering each type explicity as more specific type. For me this solution is more clear than using sub dependency resolver

var commandTypes = businessAssembly.GetTypes()
    .Where(t => !t.IsInterface && typeof(ICommand).IsAssignableFrom(t));

foreach(var commandType in commandTypes)
{
    var handlerInterface = typeof(ICommandHandler<>).MakeGenericType(new[] { commandType });
    var transactionalHandler = typeof(DeadlockRetryCommandHandlerDecorator<>).MakeGenericType(new[] { commandType });
    container.Register(Component.For(handlerInterface)
        .ImplementedBy(transactionalHandler)
        .LifeStyle.PerWebRequest);
}
