Chrome Notifications not appearing from Chrome Extension background page

Question

Using the new chrome.notifications API, I am unable to get notifications from my extension to appear. Even the most basic notification fails to appear for me, but I get no errors and the callback function is properly executed.

manifest.json

{
  "name": "notify",
  "version": "0.0.0",
  "manifest_version": 2,
  "permissions": [
    "notifications"
  ],
  "background": {
    "scripts": ["main.js"]
  }
}

main.js

window.addEventListener('load', function() {
  var opt = {
    type: 'list',
    title: 'Primary Title',
    message: 'Primary message to display',
    priority: 1,
    items: [{ title: 'Item1', message: 'This is item 1.'},
            { title: 'Item2', message: 'This is item 2.'},
            { title: 'Item3', message: 'This is item 3.'}]
  };
  chrome.notifications.create('notify1', opt, function() { console.log('created!'); });
});

When I inspect the background page, I can see "created!" in the console, but I don't ever get a notification on the desktop. I have tried a bunch of different priority values to no avail. What am I doing wrong?

You may have chrome notifications blocked. A good hint this is the case is if you aren't being constantly spammed with notifications from other websites. This answer worked for me.
