What did you do?

When I'm requesting an http2 endpoint that sets multiple cookies, not all the cookies are persisting in the cookiejar.

I don't have time to write a full mock up, but here's what I got. This test will fail

func TestCookies(t *testing.T) {

	jar, err := cookiejar.New(&cookiejar.Options{})
	if err != nil {
		t.Fatal(err)
	}

	httpClient := &http.Client{
		Jar: jar,
	}

	form := url.Values{}
	form.Add("UserName", "my-user")
	form.Add("password", "my-password")

	res, err := httpClient.PostForm("https://my-site.com/Account/Login", form)
	if err != nil {
		t.Fatal(err)
	}

	u, err := url.Parse("https://my-site.com/Something")
	if err != nil {
		t.Fatal(err)
	}

	cookies := jar.Cookies(u)
	if len(cookies) != 4 {

		data, _ := httputil.DumpResponse(res, false)
		t.Error(string(data))

		t.Fatal("unexpected number of cookies", len(cookies))
	}

}

Test output:
