  createDocument();
  let doc = content.document; <- Causes CPOW warning

  let {inspector} = yield openInspector();

  yield selectNode("div", inspector);
  yield assertCopyImageDataNotAvailable(inspector);

  yield selectNode("img", inspector);
  yield assertCopyImageDataAvailable(inspector);
  yield triggerCopyImageUrlAndWaitForClipboard(doc.querySelector("img").src, inspector); <- Causes CPOW warning

  yield selectNode("canvas", inspector);
  yield assertCopyImageDataAvailable(inspector);
  let canvas = doc.querySelector(".canvas"); <- Causes CPOW warning
  yield triggerCopyImageUrlAndWaitForClipboard(canvas.toDataURL(), inspector); <- Causes CPOW warning

  // Check again that the menu isn't available on the DIV (to make sure our
  // menu updating mechanism works)
  yield selectNode("div", inspector);
  yield assertCopyImageDataNotAvailable(inspector);
});

function createDocument() {
  let doc = content.document; <- Causes CPOW warning

  doc.body.innerHTML = PAGE_CONTENT; <- Causes CPOW warning
  let context = doc.querySelector(".canvas").getContext("2d"); <- Causes CPOW warning
  context.beginPath(); <- Causes CPOW warning
  context.moveTo(300, 0); <- Causes CPOW warning
  context.lineTo(600, 600); <- Causes CPOW warning
  context.lineTo(0, 600); <- Causes CPOW warning
  context.closePath(); <- Causes CPOW warning
  context.fillStyle = "#ffc821"; <- Causes CPOW warning
