No linenumbers in codeclimate widget

Summary

The codeclimate widget only shows line-numbers for

{
  "path": "path/to/file.sh",
  "lines": {
    "begin": 13,
    "end": 14
  }
}

while a second form exists : https://github.com/codeclimate/spec/blob/master/SPEC.md#locations

{
  "path": "path/to/file.sh",
  "positions": {
    "begin": {
      "line": 3,
      "column": 10
    },
    "end": {
      "line": 4,
      "column": 12
    }
  }
}

Steps to reproduce

codeclimate engine shellcheck produces "positions", engine fixme uses "lines"
create script.sh

#!/bin/bash

# - trigger fix-me-report ("found TODO")
# TODO testfixme
# - trigger shellcheck-report ("use quotes to prevent...")
if [ -z $PROJECTLIST ]; then
 echo dummy
fi

observe 2 new issues, fixme with linked-linenumber, shellcheck without.

What is the current bug behavior?

Widget displays:
Some Issue Text occured. in path/to/file.sh

What is the expected correct behavior?

Widget should add a line-number (and modify the link):
Some Issue Text occured. in path/to/file.sh:3

Possible fixes

https://gitlab.com/gitlab-org/gitlab-ee/blob/master/ee/app/assets/javascripts/vue_merge_request_widget/stores/mr_widget_store.js#L207 (?)
Needs something along the lines of

          } else if (issue.location.positions && issue.location.positions.begin && issue.location.positions.begin.line) {
            parsedIssue.line = issue.location.positions.begin.line;
            parseCodeQualityUrl += `#L${issue.location.positions.begin.line}`;
          }
