'Click to expand it' link on the MR page does not work
Im seeing this in staging. - Seem to have been introduced due to the 11.6 RC on staging. You can take a look at this MR page - https://staging.gitlab.com/gitlab-qa-sandbox-group/qa-test-2018-12-04-21-27-22/perf-test-project-9bdc6bfdd1a56094/merge_requests/1/diffs
Clicking on any of the 'Click to expand it' link throws the below error.
