Rev not found error for commits that exist on code host

Created by: felixfbecker

This is on https://sourcegraph.com/gitlab.com/felixfbecker/gitlab-ee@sourcegraph/-/commits :

It breaks the browser extension/native integration code intel on the MR, because it gets back a rev not found error from the backend:

I can even show files at that revision on Sourcegraph, but it does not show up in commit search and the extension gets a rev not found error.
