Disable sync-xhr in amp-iframe/amp-ad #13766
What's the issue?
Chrome 65+ allows synchronous XHR to be disabled. Blocking the UI thread on the network is a perf anti-pattern and so should probably not be allowed in AMP documents or embeds.
How do we reproduce the issue?
What browsers are affected?
Chrome for now, but at TPAC all other browsers indicated a desire to add this feature as a first step of trying to phase-out sync-xhr.
