Google Chrome and Set-Cookie?

Question

HTTP Cookies

Please tell me the correct format of HTTP header Set-Cookie.
rfc2109 says:

av-pairs        =       av-pair *(";" av-pair)
   av-pair         =       attr ["=" value]        ; optional value
   attr            =       token
   value           =       word
   word            =       token | quoted-string

Sending a GET request using Google Chrome to example.com/main/about .
I get a response along with a header:

Set-Cookie:SESSID="9l8MUBbPRhxaD2b9paYMGJ9t0Q9TLLYK"; Version="1"; Path="/"

Notice the Path="/" attribute. Nevertheless, Chrome remembers the cookie with Path: /main
If Path is sent as a token and not quoted-string, that is, Path=/ - then everything works correctly.
Where is the truth and why is Google Chrome ignoring the RFC?
