Scroller not working

[curtisjhu]

Describe the bug
Hi! just recently trying out the idyll framework. The [Scroller]...[/Scroller] components do not display the inner 'text-containers' nor the graphic component. It's just empty.

To Reproduce
Steps to reproduce the behavior:

1. Use idyll create cli command to create a 'scrollytelling' project
2. run with 'idyll'
3. Errors: The scroller components are empty.

Expected behavior
Expected text or a graphics, anything. It's just blank space

Screenshots

Desktop (please complete the following information):

• macOS Monteray 12.5
• chrome

Additional context

I've followed the docs closely. I also tried looking at other people's projects that use scroller. As I look into idyll-components/src/scroller.js line 167 seems to return an empty list of child elements. It looks like the filter function is returning false everytime because c.type.name is usually 'x'. Does anyone know why the c.type.name is x? Where is it creating react elements that are of x type?

Thanks in advance!
