this should be typed for the js compiler, so either cast, or (better)
encapsulate the "connection" inside target and expose explicit:
target.consoleAgent(), target.pageAgent(),... that will return a proper @return
types.

Partially done. I encapsulated connection. But, unfortunately, our generator
does not create type ConsoleAgent, but instance of it, thus our compiler does
not understand /** @type {!ConsoleAgent} */

I will handle this issue in a separate patch. 

     this.messages = [];
     this.warnings = 0;
     this.errors = 0;
     this._interruptRepeatCount = false;
-    InspectorBackend.registerConsoleDispatcher(new WebInspector.ConsoleDispatcher(this));
+    target.connection.registerDispatcher("Console", new WebInspector.ConsoleDispatcher(this));

encapsulate connection?

Done.
