 // Test debug events when we only listen to uncaught exceptions and a
 // Promise p3 created by Promise.race has a catch handler, and is rejected
 // because one of the Promises p2 passed to Promise.all is rejected. We
 // expect no Exception debug event to be triggered, since p3 and by
 // extension p2 have a catch handler.
