Failure (400 Bad request) in browser_ui/3_create/snippet/clone_push_pull_project_snippet_spec.rb | Create Version control for project snippets clones, pushes, and pulls a project snippet over SSH, deletes via UI

Summary

Noticed that a couple tests started failing in staging around snippets. There was a feature flag toggle for that run with gitaly_transactional_symbolic_ref_updates to true and wondering if it is related.

Also tried to test locally but that feature flag didn't exist in latest master, which could be related as well.

Failing job(s): https://ops.gitlab.net/gitlab-org/quality/staging/-/jobs/6424896#L2476

Failing spec(s):

• Create Version control for project snippets clones, pushes, and pulls a project snippet over SSH, deletes via UI
• Create Multiple file snippet behaves like copying snippet file contents copies file contents of a multi-file personal_snippet to a comment and verifies them
