Merge request "Changes" tab do not allow expanding large diffs
When creating large merge requests and visualizing large commits, the "Changes" tab shows an alert like this and the user can open the full diff.
Too many changes. [Reload with full diff] [Plain diff] [Email patch]
To preserve performance only 32 of 47 files are displayed.
That is not true, however, for when the user tries to see the changes of a large merge request that is already created. What GitLab shows is this alert, instead:
Changes view for this comparison is extremely large.
You can download it instead.
The same behaviour from the former scenarios should happen in this situation too.
I'm using GitLab 7.12.1, deployed using https://github.com/sameersbn/docker-gitlab docker image. I've just upgraded from 7.1.0, where I cannot see the large merge request diff either.
