We should add a ref selector as it improves the UX of the page. See: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/195369#note_2590697774 > rendering the ref selector would be good for UX because it: > > * Allows users to switch between branches to view the Blame across branches > * More consistent with the blob view and other repository pages | blob | blame (current) | | ------ | ------ | |  |  |
