NOT IMPLEMENTED message when run with chrome browser

I'm using the following versions:

dalekjs: 0.0.8
dalek-browser-chrome: 0.0.7

With the following simple test case:

module.exports = {
  'Google Browser Test': function(test) {
    test
      .open('https://www.google.com/')
      .done();
  }
};

When run with the chrome browser option, following is the output:

C:\Users\user1\node_modules\dalekjs>dalek test\googleBrowserTest.js -b chrome
Running tests
Running Browser: Google Chrome
OS: Windows NT 6.1 SP1 x86_64
Browser Version: 30.0.1599.101

RUNNING TEST - "Google Browser Test"

 0/0 assertions passed. Elapsed Time: 6.47 sec
[5836:9840:1112/160346:ERROR:textfield.h(176)] NOT IMPLEMENTED

It seems that the .open is causing the "NOT IMPLEMENTED", but why? The error doesn't seem to be causing any problems. I don't get this error when run without the browser option.
