[Bug 1852645] Re: WebAudio API does not behave as expected (Cannot mute videos)

** Description changed:

  I initially posted this bug to the Firefox issue tracker here:
  https://bugzilla.mozilla.org/show_bug.cgi?id=1596397, but we determined
  it was specific to the Ubuntu package.
  
  When I play the video in this JSFiddle: https://jsfiddle.net/ea9h3bg7/,
  there should be no audio. This is the behavior in the Firefox 70 build
  that you can get from Mozilla's website. However, with the Ubuntu build,
  audio is still heard.
