Out of scope

• These cases are out of scope, because they are already covered in https://gitlab.com/gitlab-org/gitlab-ee/issues/3853:

  • Epic system note: Epic mentioned in other issue
  • Epic system note: Epic mentioned in other merge request
  • Epic system note: Epic mentioned in other epic

• But they should be regression tested when this is worked on.

• Per https://gitlab.com/gitlab-org/gitlab-ee/issues/3947#note_46734408, should work on https://gitlab.com/gitlab-org/gitlab-ee/issues/3889 first, and this one will be closed in the same merge request.
