Hi! 

I have noticed that keyboard navigation doesn't work in the filter editor components inside the Filter component

Reproduction:

1. Open https://stackblitz.com/edit/react-rvwjsm?file=index.html
2. Choose "name" or "price" from the first dropdown
3. Type anything in the input field
4. Try to change the cursor position in the field using arrow keys - doesn't work

 Is there a way to enable it or go around it?
