OnContextReleased is called in the Render process immediately before the CefV8Context is released. An IPC message is immediately sent to notify the context has been released (cannot execute javascript this point). If the page had no javascript then the context would not have been created and as a result this method will not be called. Currently only called for the Main frame IsMain
