ResolveFully option does not resolve all schemas in some paths

Swagger-parser version: 2.1.1

Example swagger spec:
The test case is quite large, so I put it in a github gist. Don't be surprised by the names of the paths and schemes - I masked the critical data.

Description:
When using the ResolveFully option, I get requests with unresolved links. For example, take the request POST /v1/BusinePEH0JF. In swagger-ui it renders correctly - in the request body in the manager field, the Emplo4XN6X schema is resolved:

But swagger-parser gives this result:

Here the link is not resolved. This is most likely due to the fact that the parent schema BusinesYD77B4X in this request is stored as such in resolvedModels due to the fact that it is also used in other requests, such as POST /v1/ApprovalSetU0C9RY71SHD/manager-to-employees. Here, the manager field is empty, because this scheme has already been used above in the approver field.

Reproduction of the error:

val parseOptions = new ParseOptions()
parseOptions.setResolve(true)
parseOptions.setResolveFully(true)

val openAPI = new OpenAPIV3Parser().read(swaggerSpec, null, parseOptions)

Expected result:
Like on the first screen in swagger-ui

Thanks!

Start with OpenAPIV3Parser.read and the ParseOptions resolve/resolveFully settings, reproducing the case from the linked gist. Trace how the shared BusineYD77B4X schema is handled when parsing the two requests, then verify that the manager field and Emplo4XN6X schema are fully resolved in both paths.
