What are the action points?

Chrome, Opera and Firefox seems to handle dup cookies in the same way
(FIFO). Safari seems to order cookies. Edge leaves last cookie and always
leave broader scope (with subdomains).

Do you agree to choose one of ways above? FIFO is more widely used but
Safari-style seems to be more concise. Probably worth aligning with 6265bis.

Issue
https://github.com/httpwg/http-extensions/issues/199

Should someone (me?) open an issue for the matter on curl github?
