Note: before coding this test, please run the planned design past myself and jmspeex (or involve us in creating the design). This is Not Easy to test.

https://phabricator.services.mozilla.com/D198238 used the loopback device to a test that AEC reduces the amplitude of signal on the input device when that exactly matches the signal going to the output device.
Perhaps a similar test with an additional output from a cross-origin iframe (which would not be cancelled) could be used to verify that the AEC passes through wanted signals while reducing the echo from the same-window output.
