Symfony 4.x: Doctrine getManagerForClass() not returning the right Entity Manager

Question

I'm looking to be able to get the correct Entity Manager given an entity instance (or just classname).

It was pointed out that doctrine ManagerRegistry has the method getManagerForClass, which accepts a classname and should return the correct matching Entity Manager.

However, when I call it, it always returns the default.

orm:
    auto_generate_proxy_classes: '%kernel.debug%'
    default_entity_manager: default
    entity_managers:
        default:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: default
            mappings:
                App:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/src/Entity'
                    prefix: 'App\Entity'
                    alias: App
                gedmo_loggable:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/vendor/gedmo/doctrine-extensions/lib/Gedmo/Loggable/Entity'
                    prefix: Gedmo\Loggable\Entity
                    alias: GedmoLoggable # this one is optional and will default to the name set for the mapping
        lobbytrack:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: lobbytrack
            mappings:
                Lobbytrack:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/src/Entity/Lobbytrack'
                    prefix: 'App\Entity\Lobbytrack'
                    alias: Lobbytrack

I'm testing with an entity in the lobbytrack database, visitor.

$entityClass = 'App\Entity\Lobbytrack\Visitor';
$this->entityManager = $this->managerRegistry->getManagerForClass($entityClass);

If I inspect the returned entityManager, I see that it's getting the default entity manager, when it should be returning lobbytrack.

The config of the visitor entity puts it in the appropriate namespace, which as far as I can tell, is how it determines which manager matches which entity.

namespace App\Entity\Lobbytrack;

use Doctrine\ORM\Mapping as ORM;

/**
 * Visitor
 *
 * @ORM\Table(name="visitor")
 * @ORM\Entity(repositoryClass="App\Repository\Lobbytrack\VisitorRepository")
 * @ORM\HasLifecycleCallbacks
 */
 class Visitor
 {

I'm thinking there is something about my configuration that is breaking this, but I can't see what.

Placing the 'default' entity manager last in doctrine.yaml got this to work as expected.

orm:
    auto_generate_proxy_classes: '%kernel.debug%'
    default_entity_manager: default
    entity_managers:
        lobbytrack:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: lobbytrack
            mappings:
                Lobbytrack:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/src/Entity/Lobbytrack'
                    prefix: 'App\Entity\Lobbytrack'
                    alias: Lobbytrack
        vcenter:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: vcenter
            mappings:
                Vcenter:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/src/Entity/Vcenter'
                    prefix: 'App\Entity\Vcenter'
                    alias: Vcenter
        default:
            naming_strategy: doctrine.orm.naming_strategy.underscore
            connection: default
            mappings:
                App:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/src/Entity'
                    prefix: 'App\Entity'
                    alias: App
                gedmo_loggable:
                    is_bundle: false
                    type: annotation
                    dir: '%kernel.project_dir%/vendor/gedmo/doctrine-extensions/lib/Gedmo/Loggable/Entity'
                    prefix: Gedmo\Loggable\Entity
                    alias: GedmoLoggable # this one is optional and will default to the name set for the mapping
