What specific section or headline is this issue about?
No response
What information was incorrect, unhelpful, or incomplete?
- Timing-Allow-Origin is needed for CORS and no-cors, it's for cross-origin protection
- In the case of cross-origin iframes, responseEnd might measure when the iframe finished loading completely with all its subresources, not just the main resource.
- encoded/decoded body size are (soon to be) CORS-protected rather than TAO protected
