* DevTools transport relying on JS Window Actors. This is an experimental
* transport. It is only used when using the JS Window Actor based frame
* connector. In that case this transport will be used to communicate between
* the DevToolsServer living in the parent process and the DevToolsServer
* living in the process of the target frame.
*
* This is intended to be a replacement for child-transport.js which is a
* message-manager based transport.
