 Replying to [ticket:32865 micahlee]:

 [snip]

 > One possible solution would be to treat onion sites that load resources
 from other onion sites different than onion sites loading resources from
 clearnet sites. When it's onion -> onion, it could send the actual
 `Referer` and `Origin` headers, but when it's onion -> clearnet, it could
 strip the `Referer` header and send `Origin: null`, which is the current
 behavior.

 On the positive side, I think this seems to be worth exploring to me
 (bonus points if we have a convincing argument as to why this is (still)
 spec-compliant).
