document-field example breaks post admin page when mention is used

[shendrick]

1. Spin up the document-field example project
2. Create a Post and add an author inline with 'mention'
3. Click "Create Post".

I expect the post to save correctly.

I get this error when trying to open the new post in the admin...

TypeError: Cannot read properties of undefined (reading 'mention')

For some reason, it now lets me edit it again, but the relationships aren't dropdowns anymore and just hardcoded text..

Adding mention...

After saving and reloading...

Yeah, i have same issue.

When i upgraded @keystone-6/fields-document from "3.0.0" to "4.0.0", i faced with this bug.
