Describe the bug

When a field in the response body is prefixed with a path segment from the request, the text after that path segment is not included in the response body.

Expected behavior:

WireMock should evaluate all of the text in the mapping and include all of it in the response.

Test to reproduce

Mapping:

[
  {
    "Request": {
      "Path": "/path",
      "Methods": [
        "GET"
      ]
    },
    "Response": {
      "StatusCode": 200,
      "BodyAsJson": {
        "field": "{{request.PathSegments.[0]}}text_being_removed_incorrectly"
      },
      "UseTransformer": true,
      "Headers": {
        "Content-Type": "application/json"
      }
    }
  }
]

Request: GET http://{WIREMOCK_SERVER_HOST}/path
Expected response:

{
  "field": "pathtext_being_removed_incorrectly"
}

Actual response:

{
  "field": "path"
}

This issue only occurs when the request path segment is the prefix of a field in the response body. Adding any characters before the request path segment resolves the issue.

Mapping:

[
  {
    "Request": {
      "Path": "/path",
      "Methods": [
        "GET"
      ]
    },
    "Response": {
      "StatusCode": 200,
      "BodyAsJson": {
        "field": "prefix{{request.PathSegments.[0]}}text_being_removed_incorrectly"
      },
      "UseTransformer": true,
      "Headers": {
        "Content-Type": "application/json"
      }
    }
  }
]

Request: GET http://{WIREMOCK_SERVER_HOST}/path
Response:

{
  "field": "prefixpathtext_being_removed_incorrectly"
}
