[Jun Mukai, 2014/08/19 17:22:35]

Note that VK depends on content layer (because VK is a webui), which makes
harder to add logic to screen manager.

[oshima, 2014/08/19 18:05:49]

What I meant is to move the observer interface to screen instead.
If this is only place that needs take an action, we may leave it as is.

Do we need to keep this?
athena_unittests now depends on content layer, so initialization with
TestBrowserContext would be acceptable.

[oshima, 2014/08/19 18:05:49]

That's not enough because test doesn't initialize shell extension.
We'll remove it, but not ready yet.
