Child fields in objects (in arrays) do not render

## Reproduction
When adding child fields in an object field, they do not render. I'm using this in an array field as below, and am stumped as to how to edit the child field in question.
```
// ...other componentBlock definitions
faq: component({
preview: (props) => {
return (
[placeholder preview]
)
},
label: 'FAQ',
schema: {
title: fields.text({ label: 'Titel' }),
questions: fields.array(
fields.object({
question: fields.text({
label: 'Vraag'
}),
answer: fields.child({
kind: 'inline',
placeholder: 'Antwoord',
links: 'inherit'
})
}),
{
label: 'Vragen',
itemLabel: props => { return props.fields.question?.value || 'New item' }
}
)
}
}),
```

## Expectation
The child field to render within the popup of the array field's object field.

## For context
Node 18.14, recent versions of Chrome and Firefox.
