You can use channel <= DEV to cover these cases, as well as "trunk" (which is
CHANNEL_UNKNOWN).

I don't want to include CHANNEL_UNKNOWN. That way, we can still debug issues in
our own builds and compare old-style Panels with refactored Panels behavior.

       // Note: Panels ignore all but the first url provided.
       Panel* panel = PanelManager::GetInstance()->CreatePanel(
           title, window_profile, urls[0], panel_bounds.size());
