MIME/Content type issue when viewing raw html code

I have an .html file committed into a Git repository, and according to FISHEYE_HOME/raw-mime.types when the file extension is html or htm the file mime type should be text/html.

I want to see the raw content in FishEye by accessing http://localhost:8060/browse/~raw,r=HEAD/MyGitRepo/TEST.html, but the problem is that the Content-Type is text/plain.

cURL also says that the the content type is text/plain:

curl -I http://localhost:8060/browse/~raw,r=HEAD/MyGitRepo/TEST.html
HTTP/1.1 200 OK

Content-Disposition: inline
Content-Type: text/plain;charset=UTF-8
Content-Length: 99

Is there a way to specify the content type, such that, for example, when the file is HTML,
then FishEye would return the contents with a Content-Type set to text/html?
