—disable-web-security not working for cross-origin frame

Reported by draclo...@gmail.com, Jun 12 2018

Issue description

UserAgent: Mozilla/5.0 (iPhone; CPU iPhone OS 11_2_6 like Mac OS X) AppleWebKit/604.5.6 (KHTML, like Gecko) Version/11.0 Mobile/15D100 Safari/604.1

Steps to reproduce the problem:
1. Launch chrome with —disable-web-security —user-data-dir=xxx
2. Open my page which has an iframe from different domain
3. Call a JavaScript method within the iframe from main page

What is the expected behavior?
The JS call should succeed

What went wrong?
An exception thrown said cross-origin frame access is blocked (something like that)

Did this work before? Yes 66

This is probably due to site isolation, which is being enabled in M67, and sounds similar to issue 849708.  You can confirm by checking if setting chrome://flags/#site-isolation-trial-opt-out to "Opt out" resolves things.
For now, I'll merge this report to that issue, and we can continue the discussion there.
