Symfony service instantiated on every request

Question

I have a service called TennantContext which deals with all tenant related functions including keeping track of the current tenant the user has active.

I was under the impression that once instantiated that the service is never instantiated again? Am I correct.

I have the following issue:

I am Injecting the TenantContect service in to multiple controllers and event triggers, but every time it is injected it is being instantiated again, e.g. the constructor is being run again and all previous values in the service have been reset:

TenantContext:

class TenantContext
{
    private $tenant;
    private $isInitialized = false;
    ...
    ...
    public function __construct(
        Security $security,
        LoggerInterface $logger,
        UserService $userService,
        EntityManagerInterface $entityManager
    )
    {
        $this->logger = $logger;
        $this->logger->info("YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY: Tenant instantiated");
        ...
        ...
    }

This is instantiated first with my LoginEventListener which on successfuly login sets the tenant in the context:

class LoginListener
{
    /**
     * 
     * @var EntityManagerInterface
     */
    private $em;

    /**
     * 
     * @var TenantContext
     */
    private $tenantContext;

    /**
     * 
     * @var LoggerInterface
     */
    private $logger;

    public function __construct(
        EntityManagerInterface $em,
        LoggerInterface $logger,
        TenantContext $tenantContext
        )
    {
        $this->em = $em;
        $this->logger = $logger;
        $this->tenantContext = $tenantContext;
    }

    public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
    {
        $this->logger->info("------------------------------------- onSecurityInteractiveLogin");
        // Get the User entity.
        /**
         * 
         * @var User $user
         */
        $user = $event->getAuthenticationToken()->getUser();
        $this->tenantContext->initialize($user->getTenant());
    }
}

This is working perfectly, however when I navigate to another page (using the routes e.g. In Twig: {{ path('dashboard') }}

Log:

I can see tfrom the logs that the constructor is meing called again, this happens for every request.

How do I get TenantContext to be one instance for the whole session?

Thanks in advance.

Edit: It seems this happens on other services too, I added some logging on another service I have and it performs the same. I haven't noticed this so far as all my services do not hold any data, just functions.
