- [ ] `TPL_SUGGESTBOX_LOADING` is never used. Remove unused/incomplete features.
- [ ] Rename `suggestBox` and `words` to private properties. Also the names should reflect the that they are `Nodes`.
```js
instance._suggestBoxNode = A.Node.create(TPL_SUGGESTBOX);
instance._suggestBoxWordsNode = A.Node.create(TPL_SUGGESTBOX_WORDS);
```
