Is your feature request related to a problem? Please describe.
There is a timeout on https://scholia.toolforge.org/P921

The current SPARQL is

# tool: scholia
PREFIX target: <http://www.wikidata.org/prop/direct/P921>

SELECT ?item ?itemLabel ?property_value ?property_valueLabel WHERE {
  ?item target: ?property_value .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en" . }
}
LIMIT 500

Describe the solution you'd like
The labeling should be performed after the LIMITing.
