User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.62 Safari/537.36

Steps to reproduce:

1. Go to https://test.shhnjk.com/local_scheme.html


Actual results:

Firefox takes 'self' as embedding document's origin.


Expected results:

According to following comment, self should be local scheme itself.

I'm not convinced Firefox is wrong (as opposed to the spec language being less useful).

In any case this is a spec compliance issue and doesn't need to be a hidden security bug.
