Unable to collect schemas recursively when using tuples

[MitsuPa]

#[derive(ToSchema, Serialize, Deserialize)]
struct B {
  test: String,
}

#[derive(ToSchema, Serialize, Deserialize)]
struct A {
  b: B,
}

#[utoipa::path(
  method(post),
  request_body(
    content = (A, String)
  ),
  path = "/test",
  responses(
      (status = OK, body = (A, String))
  ),
  tag = "statistics",
)]
async fn get_statistics(Json(req): Json<(A, String)>) -> Json<(A, String)> {
  print!("{:?}", req.1);
  Json((req.0, req.1))
}

Could not resolve reference: JSON Pointer evaluation failed while evaluating token "B" against an ObjectElement

        "requestBody": {
          "content": {
            "application/json": {
              "schema": {
                "type": "array",
                "items": false,
                "prefixItems": [
                  {
                    "type": "object",
                    "required": [
                      "b"
                    ],
                    "properties": {
                      "b": {
                        "$ref": "#/components/schemas/B"
                      }
                    }
                  },
                  {
                    "type": "string"
                  }
                ]
              }
            }
          },

No B in #/components/schemas/

Please check it, thank you very much!

Probably a bug somewhere in automatic schema collection which does not take account all the types of tuples when collecting the schemas with tuples. This indeed needs some investigation for to find the solution.
