I believe this is a bug.
Just pushed a commit to GitHub. This triggered a PR branch build on CI, but it fails with an error that it can’t find the commit:
Warning: Permanently added 'github.com,192.30.253.112' (RSA) to the list of known hosts.
fatal: Could not parse object 'ac1d28d8e598ca3ea9c78e35db32af206b653603'.

Maybe I have something configured wrong?
