Code Quality MR widget struggles with big codelimate.json files

We got a quiet big project on our GitLab instance and tried the new codeclimate feature. After running codeclimate for the first time it generated a 25MB codeclimate.json file.

If we now open a new merge request, the browser gets unresponsive after a few seconds while trying to diff both files (I guess).

As customer I would assume that the codeclimate feature also can handle/analyze bigger files.
