in our special case the request is made with the following param:
`origin` = `"rtcweb://peerconnection"`
`options.origin` = `"http://example.com"` where `example.com` is the site we are logged into.

This change allows us to verify identity with origin site, while generating an assertion for the made up origin `rtcweb://peerconnection`, a url that is specifically crafted to not represent something that looks like a real website, making it unspoofable.
