Why does Wikidata's query interface return no results for entities with an id of Q10000001 or higher?

Question

I have this SPARQL query to return an item's label and the url of a Wikipedia article:

PREFIX schema: <http://schema.org/>
PREFIX wd: <http://www.wikidata.org/entity/>
SELECT ?article ?itemLabel WHERE
    { FILTER ( ?item = wd:Q10000000 )
      ?article  schema:about       ?item ;
                schema:inLanguage  "en" ;
                schema:isPartOf    <https://en.wikipedia.org/> .

      SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    }

This works as expected, but as soon as I substitute the id with Q10000000 or any higher number included, it yields no result. Not only to the entities I checked exist, but also does the query editor display a label when hovering over the id in that expression.

What is causing this behaviour and how can I adjust the query to get results for entities with ids that have an id of Q10000001 and higher?

There isn't an article about Татьяна Колотильщикова in English Wikipedia.

Just comment out the second and the third triple patterns in your query.

Or try e. g. Q11000001 instead of Q10000001.
