Customer https://gitlab.my.salesforce.com/0016100001FUhCS is seeing something similar to this.

Steps to reproduce

See below.

Example Project

If we go to https://gitlab.com/gitlab-org/gitlab-ee/commits/master/doc/administration/auth/ldap.md we can see f257c15d is the latest commit but if we switch to the file view at https://gitlab.com/gitlab-org/gitlab-ee/blob/master/doc/administration/auth/ldap.md it shows as 0c411a99.

What is the current bug behavior?

It's not showing the latest commit.

The latest commit could show up as default on that branch.
