Add spec to ensure MR diffs are highlighted (!21410) · Merge requests · GitLab.org / GitLab FOSS · GitLab

Sean McGivern requested to merge assert-that-mr-diff-is-highlighted into master Aug 29, 2018

This adds a case that I think was missing from https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/2463. It's minor, but I think it is worth testing.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/50793.
