I cannot reproduce the issue with git v2.21 and git-lfs v2.4.2. However, the problem is reproducible with git v2.7.1 and git-lfs v2.3.4. Please, make sure you use current version of those tools.

Update: As far as I can tell, the minimum version of git that doesn't have the problem is 2.8 (tested with 2.8.4)
