I don't know if this is the case for this particular extension. However, for most Chrome extensions, they can only use those shortcuts if they are opened in a separate window. You can select this option by right clicking on the app in the new tab page. I know that Chrome Remote Desktop can only use Ctrl-W in a separate window, but it works fine once it is in a separate window.
