This is a follow-up to issue #576241, where such MRs were erroring with a 500. This was resolved with https://gitlab.com/gitlab-org/gitlab/-/merge_requests/210440, but the problem persists that the commit count will be missing. ## Goal Optimize the performance of commit count calculation and display on the MR creation page so the count can be shown again without impacting page load times. ## Proposal TBD. Maybe we could fallback on the frontend count?
