Word-Based Animations not working

Hi, I performed a clean install of the Agency Site skeleton and I installed Shortcode UI 2.0.0 and Shortcode Core 2.2.1, nothing more.
Then on the Header page I added the following text:

```
# I am myself
[ui-animated-text words="pizza, chips, steak" animation="clip" element="h2"]and I love[/ui-animated-text]
```

The animation isn't working and as a result all 3 words are added to the end of the line as you can see on http://www.dimitri.eu/marleen/

Here is a zip file of the site: [site.zip](https://github.com/getgrav/grav-plugin-shortcode-ui/files/285084/site.zip)

Is there something I did wrong?
