Also note that the old Options code (and current MD Settings "About" code), receives the product name as a string from the browser, it is not part of the image being displayed. The assets provided at comment 16 have the product name as part of the image. Is this change intentional?

Author: dpapad <dpapad@chromium.org>

MD Settings: About page, fix bug causing update status message to not update.

The bug was twofold
 1) Non ChromeOS data binding should not depend on targetChannel_, since
    targetChannel_ is only defined for ChromeOS.
 2) There was a typo in the HTML data binding, s/targetChannel/targetChannel_.

Previous test was only checking that the update status icon was updated, without
making assertions about the update status message.

Per 19, that change is intentional. The product name is now part of the logo. 

Per 18, links to chromium assets below. There is no notion of an OS in the branding of chromebooks anymore so use "Chromium" for both browser and OS.
