Steps to reproduce

Visit https://www.hotmail.com with F12 tools open. Note there are no errors reported for cookie issues. Check network tab or other network capture to see many Set-Cookie headers like

Set-Cookie: bellca=; domain=.mail.live.com; expires=Thu, 01-Jan-1970 12:00:01 GMT; path=/; secure

    • I expect to see an error message in the F12 console window whenever a Set-Cookie header is rejected or ignored. This includes the example here where the domain is invalid as well any others. Other examples include a Set-Cookie header being malformed or even a third party cookie being rejected because of the user selected this in the settings UI. In each case the message should identify exactly why a cookie was rejected.
