Anonymization fails to remove Gravatar

I was testing the WP GDPR Compliance plugin, and asked to anonymize one of my own comments. I wiped out my name and email address, but left my Gravatar photo intact…
AND the image still links to the website that is tied to my Gravatar account. That makes the anonymization effort very ineffective. I think this is an urgent “must-fix” issue.
