When cxf service is deployed to child container SwaggerFeature uses root container port instead

Using a simple fabric with a root and one child on the same host deploying a cxf service shows a 'Location' of http://192.168.2.221:8182/cxf/ on http://localhost:8181/hawtio/fabric/api. However, clicking on the swagger link, then expanding the operation and clicking the 'Try it out!' button show's a 'Request URL' with 'http://localhost:8181/cxf//operation'.

Note that setting the basePath attribute on the SwaggerFeature in the blueprint xml to the empty string to force cxf to calculate the path from the endpoint address results in similar behaviour with localhost port 8181 being used.
