[phoet]

the output of trackjs is a bit more helpful:

  return [".intercom-launcher-frame", "#intercom-container",
    ".intercom-messenger", ".intercom-notifications"
  ].some(function(e) {
    var t = window.parent.document.querySelector(e); // window.parent is null
    if (t) {
      var n = t.getBoundingClientRect();
      return n && n.width > 0 && n.height > 0
    }
  })

@phoet did you end up working around this or just ignoring it?

[phoet]

Neither, ignored the errors
