Hint displays incorrect when query-input has own styles

Problem appears when query-input has inline style or css-class or computed css-style like 
```css
div input { 
    font-size: 200%; 
}
```

This issue could be fixed if I add cssClasses .tt-query, .tt-hint everywhere in my site.css file.
But what if I don't have access to that file or I want to display few different autocompletes on the page?
Would be fine if plugin can take styles for hint from requested element.
