symfony: [DependencyInjection][Bug] Cryptic service name with anonymous service as argument

While working around #26629, I moved my service into a separate file, like this:

    <services>
        <service parent="liip_imagine.imagick" id="image.imagine">
            <call method="setMetadataReader">
                <argument type="service">
                    <service id="App\Infrastructure\Imagine\Metadata\ExifMetadataReader" lazy="true"/>
                </argument>
            </call>
        </service>
    </services>

This produces a very cryptic error (note the name, also the class is not set, but the ID is):

The definition for "1_~t2jBfn7" has no class. If you intend to inject this service dynamically at runtime, please mark it as synthetic=true. If this is an abstract definition solely used by child definitions, please add abstract=true, otherwise specify a class to get rid of this error.
