ReflectionException when (de)serializing unless fully qualified classname is used

Trying to unserialize a JSON structure and hitting:

Fatal error: Uncaught ReflectionException: Class SearchDashboardsAndFolders does not exist in /Users/andig/htdocs/grafana-serializer/vendor/jms/metadata/src/MetadataFactory.php:170

The same happens when serializing. It seems that for de/serialization to work, type annotations need to use the fully qualified classname as in:

namespace Andig\GrafanaSerializer\Model;

use JMS\Serializer\Annotation\Type;

class Dashboard
{
    /**
     * @Type("array<Andig\GrafanaSerializer\Model\Panel>")
     */
    public $panels;
}

It is not sufficient to use the short version although the class exists in the namespace:

    /**
     * @Type("array<Panel>")
     */
    public $panels;

Is this the expected behaviour?

I guess I just have to accept that the class names must be fully qualified...
