Similar to the sandboxed plugins, I think this is another test we should try to
write without using the deprecated plugin. We can just use a message listener on
the element to listen for the 'loaded' message from the non-deprecated plugin.
Then we won't need onNew either.

As discussed, we can use the "regular" plugin and test postMessage itself (for
both positive and negative testing) rather than relying on posted message. It
makes this test simpler and faster.

     plugin.setAttribute("onNew", "loadedSecond()");
     document.getElementById("plugins").appendChild(plugin);
     window.setTimeout(done, 5);
