This page contains no <audio> or <video> element and produces
no audio output. With the accompanying renderer-side patch applied to a
Windows Chrome build, loading this page causes the tab to display the
"audio playing" indicator and WebContents::IsCurrentlyAudible()
to return true in the browser process.
The patched renderer (simulating a compromised renderer) sends
InterfaceFactory.CreateMediaFoundationRenderer to obtain the
AudibilityBypassAuthorization stamp, then drives the
MediaPlayerObserver pipe with a fake "audible, not using audio
service, playing" sequence. No real media pipeline is ever created.
