See background in issue 879883, in non-NS path ChromeResourceDispatcherHostDelegate uses UserScriptListener::CreateResourceThrottle to block requests until content scripts have been loaded from extensions. This is not implemented with NS enabled.
Requesting a merge to M70 for change in #7, the change in #3 has been in canary, and there are just unit test changes needed for the reland.
This change fixes a regression in content script loading in network service that will be good to have when we enable on Beta.
This bug requires manual review: Reverts referenced in bugdroid comments after merge request.
Please contact the milestone owner if you have questions.
