Collapsed diff discussions are hard to distinguish

Summary

If you have many resolved diff discussions on a merge request, you need to toggle all of them to find a specific one.

Steps to reproduce

  • create a merge request
  • leave many diff discussions
  • resolve all of them
  • try to find a specific one

Example Project

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28216

What is the current bug behavior?

You see a lot of collapsed discussions that cannot be distinguished:

many-resolved-discussions

What is the expected correct behavior?

Maybe display at least the file name and the first comment—similar to non-diff discussions:

collapsed-non-diff-discussion

I'm not quite sure what should happen with the diff though.
