 --VERIFIER NOTES-- 
RFC 6455 defines this field in Section 9.1 as:

         extension-list = 1#extension
         extension = extension-token *( ";" extension-param )

While the reporter is noting the ";" between extension-token and extension-param, the separator between two extension elements is found in the definition of "#" from RFC 2616:

   #rule
      A construct "#" is defined, similar to "*", for defining lists of
      elements. The full form is "<n>#<m>element" indicating at least
      <n> and at most <m> elements, each separated by one or more commas
      (",") and OPTIONAL linear white space (LWS). This makes the usual
      form of lists very easy; a rule such as
         ( *LWS element *( *LWS "," *LWS element ))

Thus, as is typical in HTTP fields other than Cookie, the delimiter between outermost elements is "," and ";" is an internal separator within an element.
