Example for "Trigger" on Neo4j Webpage is not working as expected

The first example on the Neo4j documentation for "triggers" Triggers - APOC Extended Documentation is not working: The process does not terminate at all. I am running Neo4j 4.1.3 and APOC 4.1.0.6.

Is there a general issue with the "after" trigger that needs to be fixed or something special with that example?
