Looking for other third-party SPs that fail with stricter SameSite settings

[Cantor, Scott]

Here's the Canvas explanation:

https://bugzilla.mozilla.org/show_bug.cgi?id=1550032

They claim FF has a bug that is preventing them from setting the cookie with SameSite=None, so that's why it's working in Chrome now but not in FF.

I don't know exactly what WebExtensions is, but I'm guessing maybe the gist is that setting the cookie via Javascript doesn't work and they must be doing that.
