Chrome Version: (copy from chrome://version)
OS: (e.g. Win10, MacOS 10.12, etc...)

What steps will reproduce the problem?
(1) Create a widget with a ChildView child that has a connection attribute referencing a ChildViewConnection (to host the web_runner module).

(2) Start the web_runner module (in the ChildView) as follows:

    StoryPuppetMasterProxy storyMaster = StoryPuppetMasterProxy();

    _puppetMaster.controlStory(_storyName, storyMaster.ctrl.request());

    IntentBuilder intentBuilder =
        IntentBuilder.handler('https://www.youtube.com/tv');

    List<StoryCommand> commands = []
      ..add(
        StoryCommand.withAddMod(AddMod(
            modName: [_moduleName],
            intent: intentBuilder.intent,
            surfaceRelation: SurfaceRelation(
              arrangement: SurfaceArrangement.sequential,
              dependency: SurfaceDependency.dependent,
              emphasis: 1.0,
            ),
            surfaceParentModName: [])),
      )
      ..add(StoryCommand.withSetFocusState(SetFocusState(focused: true)))
      ..add(StoryCommand.withFocusMod(FocusMod(modName: [_moduleName])));

    storyMaster
      ..enqueue(commands)
      ..execute((ExecuteResult result) {
        if (childViewConnectionListenable.value == null) {
          _storyProvider.getController(
              _storyName, _storyControllerProxy.ctrl.request());
          final viewOwner = InterfacePair<ViewOwner>();

          _storyControllerProxy.start(viewOwner.passRequest());

          childViewConnectionListenable.value =
              ChildViewConnection(viewOwner.passHandle());

          notifyListeners();
        }
      });



(3) Attempt to update (or start anew) the module with a new url like this:

    StoryPuppetMasterProxy storyMaster = StoryPuppetMasterProxy();

    _puppetMaster.controlStory(_storyName, storyMaster.ctrl.request());

    IntentBuilder intentBuilder = IntentBuilder.handler(
        'https://google.com');

    List<StoryCommand> commands = []..add(
        StoryCommand.withAddMod(AddMod(
            modName: [_moduleName],
            intent: intentBuilder.intent,
            surfaceRelation: SurfaceRelation(),
            surfaceParentModName: [])),
      );

    storyMaster
      ..enqueue(commands)
      ..execute((ExecuteResult result) {});




What is the expected result? No exception thrown (and maybe the mod is updated or restarted with the new url?)

What happens instead? An exception is thrown like so:
