     * Verifies that when eager loading is triggered, proxies are kept managed.
     *
     * The problem resides in the refresh hint passed to {@see \Doctrine\ORM\UnitOfWork::createEntity},
     * which, as of DDC-1734, causes the proxy to be marked as un-managed.
     * The check against the identity map only uses the identifier hash and the passed in class name, and
     * does not take into account the fact that the set refresh hint may be for an entity of a different
     * type from the one passed to {@see \Doctrine\ORM\UnitOfWork::createEntity}
     *
     * As a result, a refresh requested for an entity `Foo` with identifier `123` may cause a proxy
     * of type `Bar` with identifier `123` to be marked as un-managed.
