question for request/response fields snippet with ResourceSnippetParameters

Hi. I have a question about generating request/response fields snippets with MockMvcRestDocumentationWrapper.

I'd expected documenting with only MockMvcRestDocumentationWrapper and ResourceSnippetParameters, but request/response fields snippets were not generated at build time while other snippets(parameters, etc) were successfully generated. (Code right below)

```
andDo(MockMvcRestDocumentationWrapper.document("onOrderApproved",
resource(ResourceSnippetParameters.builder()
.requestFields(
fieldWithPath("approvalNumber"),
fieldWithPath("expectedAt")
)
.responseFields(
fieldWithPath("code"),
fieldWithPath("message")
.requestSchema(new Schema("OrderApproveRequest"))
.responseSchema(new Schema("OrderApproveResponse"))
.build()
)))
```

However, adding MockMvcRestDocumentationWrapper.document without ResourceSnippetParameters, request/response fields snippets are successfully generated. (Code right below)

```
andDo(MockMvcRestDocumentationWrapper.document("onOrderApproved",
requestFields(
fieldWithPath("approvalNumber"),
fieldWithPath("expectedAt")
),
responseFields(
fieldWithPath("code"),
fieldWithPath("message")
))
)
.andDo(MockMvcRestDocumentationWrapper.document("onOrderApproved",
resource(ResourceSnippetParameters.builder()
.requestFields(
fieldWithPath("approvalNumber"),
fieldWithPath("expectedAt")
)
.responseFields(
fieldWithPath("code"),
fieldWithPath("message")
.requestSchema(new Schema("OrderApproveRequest"))
.responseSchema(new Schema("OrderApproveResponse"))
.build()
)))
```

Is there any other way to generate all necessary snippets with only one set of MockMvcRestDocumentationWrapper.document code per an API?
