Cookies: Test IDN/non-ASCII in domain attributes
This is for httpwg/http-extensions#1707. I took some inspiration from #26170 and used a python server instead of a header file in order to better control which bytes are served as part of the header. The test runs exclusively on the élève. subdomain through opening a new window that then runs all test and reports back to the main test window.
