Environment and versions

To Reproduce
Steps to reproduce the behavior:

1. Go to https://eui.elastic.co/#/forms/search-bar
2. Click any of the "Try out this demo on Code Sandbox"
3. When the sandbox loads, you'll receive an error Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
4. Change the index.js import: import { Demo } from './demo'; -> import { SearchBarFilters } from "./demo";
