sponsored_visit_no_triggering_url:
type: counter
description: >
Number of sponsored visits that could not find their triggering URL
in history. We expect this to be a small number just due to the
navigation layer manipulating URLs. A large or growing value may be
a concern.
This metric was generated to correspond to the Legacy Telemetry
scalar places.sponsored_visit_no_triggering_url.
