Why does Symfony 2.3 logout a user with ROLE_IDDQD?

Question

User identification

Good morning.
Today is Friday, and as always, unusual things are happening.
There is a project on Symfony 2.3. The onKernelRequest event implements dynamic routing. In fact, we define the control by URL and slip it into the system.
It would seem that everything is fine. But, if the user has the ROLE_IDDQD role, then he is automatically logged out by the system. If you log in with REMEMBERME, then the authorization is still saved thanks to the cookie, but ... logout stops working.
Tried disabling the option for iddqd:

jms_security_extra:
    enable_iddqd_attribute: false

I tried to find out at what point everything breaks down: after I do
return new Response('any content');
authorization in the controller, it crashes.
Tried updating all dependencies. Did not help.
I found out that the whole point is in this non-standard routing, tk. If the route is hardcoded, then everything works fine. The method itself was taken somewhere on the Internet, figured out what was what and slightly modified it:

public function onKernelRequest(GetResponseEvent $event)
{
    if (HttpKernel::MASTER_REQUEST != $event->getRequestType()) {
        return;
    }

    $request = $event->getRequest();

    if ($request->attributes->has('_controller')) {
        return;
    }

    if (!$this->currentNode->hasCurrentPath()) {
        $this->currentNode->setCurrentPath(mb_strtolower($request->getPathInfo()));
    }

    if (!$this->currentNode->hasNode()) {
        return;
    }

    try{
        list($bundle, $controller) = explode(':', $this->currentNode->getNode()->getController()->getController());
        $controllerFilePath = $this->kernel->locateResource($bundle).'Controller/'.basename($controller).'.php';

        $routeCollection = $this->annotationFileReader->load($controllerFilePath);
        $routeCollection->addPrefix($this->currentNode->getNode()->getUrl(true));
    } catch (\Exception $e) {
        return;
    }

    $matcher = new UrlMatcher($routeCollection, $this->router->getMatcher()->getContext());

    try {
        $params = $matcher->match($this->currentNode->getCurrentPath().'/');
    } catch (ResourceNotFoundException $e) {
        try {
            $params = $matcher->match($this->currentNode->getCurrentPath());
        } catch (ResourceNotFoundException $e) {
            return;
        }
    }

    $params['node'] = $this->currentNode->getNode();

    $request->attributes->add($params);
    unset($params['_route']);
    unset($params['_controller']);
    $request->attributes->set('_route_params', $params);
}

If the user does not have the ROLE_IDDQD role, then everything works as it should. Maybe someone will throw an idea in which direction to dig?
