The feed entry for test notification is missing the icon. I guess it should use default icon.
How to reproduce:
- log in
- go to http://secure.phabricator.com/settings/user/username/page/desktopnotifications/ (replace username with your username)
- click on Send Test Notification button
- go to homepage
- look at the feed (see image below)
