This is expected because the test page accesses multiple APIs (or accesses the same API multiple times). We'll print a message for each assess. I made a similar test page that only checks cookies, and you'll see two warning messages on the first visit (since it will both read document.cookie and then write document.cookie) and only one message on the second visit (since it only reads document.cookie when the result is non-empty). See: https://senglehardt.com/test/dfpi/simple_only_cookies.html.
