There is a lot needed all at once to actually inspect a tab's DOM tree. It begins with requesting a "watcher" from a TabActor. It seems there can be many types of watchers, but here we implement the "frame" watcher only. The watcher creates an "inspector", which in turn creates a "walker", which is the actor ultimately responsible for serializing and inspecting the DOM tree. In between all that, the DevTools client will send a handful of other informational requests. If we do not reply to these, the client will not move forward with the walker. For example, the CSSPropertiesActor will be asked for a list of all known CSS properties.
