Custom color formating lost after feeding data from database using React

```


```

The above code works just fine when using html. However, in a react component, css styles get stripped.

##### Details

* Trix version: 1.3.1
* Browser name and version: Google Chrome, Firefox and Explorer
* Operating system: Mac Os

Reproduce the example using the hidden input with id "trix-input" and the element inside a React component, comparing it with the plain HTML version. Check where the React-rendered value is handed to Trix and determine why the inline color style is stripped. Done means the red formatting remains in Chrome, Firefox, and Internet Explorer with Trix 1.3.1.
