[Bug] subcomponent JSDocs & props are replaced by the parent's JSDocs & props

[humphreyja]

Describe the bug

When using subcomponents (example: <SegmentedControl.Button>), the documentation in the manifest will completely replace any props or JSDocs you may have for the subcomponents with the docs & props for the parent component.

Steps to reproduce the behavior

1. Add a tsx component <Parent> with JSDocs and props.
2. Add a child tsx component <Child> with JSDocs and props.
3. Assign the child to the parent as a subcomponent. Parent.Child = Child.
4. View the result http://localhost:8080/manifests/components.html#filter-all. Child will show the parent's docs.

Expected behavior

The child's props and JSDoc should be used instead of being overwritten by the parent's props and JSDoc.
