WHY ARE  YOU SHOUTING?

I.e. does ADVIEW really need to be all-caps? Generally tag names are lower case.

I don't need to use all-caps here. I needed to use all-caps in another file
(ad_view.js, tagWatcher).

+
+  adview.addEventListener("loadcommit", function() {
+    adview.contentWindow.postMessage({
+      message: "display-first-ad",
+      publisher_data: "data"
+    }, "*");
+  })
+
+  window.addEventListener("message", function(event) {
+    if (event.data.message == "ad-displayed") {
+      console.log("ad-displayed: " + event.data.data.ad_size.height);
+      chrome.test.sendMessage("ad-displayed");
+    }
+  })
+
+  adview.setAttribute("src", guestURL);
+});
