Chrome retains google.com site data despite the delete-on-close default

Sources: primary, discussion
Summary: Jeff Johnson reports that Chrome retains google.com site data after the browser closes, with the delete-on-close setting active. He reproduced the behavior on two Macs running Chrome 152.0.7977.83, with the default search engine set to DuckDuckGo and Chrome sign-in disallowed. Google has published no confirmation and no bug ID, and the report covers macOS only.
Why it matters: A privacy control the user set explicitly does not hold for the one site the vendor owns, and the same class of bug was reported and fixed six years ago.
Follow-up: Watch for a Google confirmation, a tracked bug ID, and whether the behavior appears outside macOS.
