I think we need to change this to
```js
 onIcc(false, function() {
         next();
  }); 
```
Or sometimes it would fail at this point, in my test.
e.g. focus on an input field in other apps to input some words, and then try to run this IME test. 

BTW, I am kind-of confused why we need this inputcontextchange events for setup()?
Can you help to explain it in more detail for me?

Thanks.
