The tracker policy document deduped third parties by name and kept the
first-seen row wholesale. Org third parties are appended before catalog
common vendors so user-editable data wins, but an org row may leave the
description or privacy policy URL empty. In that case the early return
discarded the later common-vendor row entirely, dropping metadata that
would have completed the document.
Track the kept row by name and backfill only its empty fields from later
duplicates, so org data still wins while common-vendor metadata is no
longer lost.
