Removed LFS files aren't shown in the MR diff view

Summary

I created an MR that removes an LFS-tracked file and adds another. The added LFS pointer file is shown, but the removal is not visible.

Steps to reproduce

  • git add <file-in-file>
  • git rm <file-in-lfs>
  • `git commit -m 'foo'
  • git push -o mr.create
  • View the MR

Example Project

Consider this MR: https://gitlab.com/lupine/purple-plugin-delta/merge_requests/9/diffs

In the command line, I can see vendor/deltachat-0.35.0.tar.gz is gone, but in the web UI, I cannot:

lupine@gitlab-t470p:~/dev/ur.gs/purple-plugin-delta$ git diff --stat master
 .gitattributes                      | 3 +--
 .gitlab-ci.yml                      | 2 +-
 vendor/deltachat-core-0.35.0.tar.gz | 3 ---
 vendor/deltachat-core-0.41.0.tar.gz | 3 +++

It's not visible in the commit view either: https://gitlab.com/lupine/purple-plugin-delta/commit/897bf1e96f25fb9ef33e53d954af8a4d388c29b8
