This changeset fixes a few use case:
- When referring to the Privacy Policy page, "Privacy Policy" should use capitalization on "Privacy Policy", but "page" should remain lowercase;
- When referring to the fact that a website needs, let's say "a relevant privacy policy", "privacy policy" should stay lowercase.
This changeset also updates other small capitalization issues.
