schema tool does not pull the top level comment on the resource.

This one:

```
openAPIV3Schema: &openAPIV3Schema
description: 'some comment on the toplevel struct'
type: object
....
```

Locate the schema tool that processes the shown openAPIV3Schema resource and trace how its top-level description is handled. Reproduce the case from the issue, then verify that the generated result retains the comment on the top-level resource.
