Merging pull requests not working with tracked LFS files

Description

Branches can be merged by local clients(git cli/Github for Windows) with push but not with web interface.

I am using LFS too, haven't encountered the problem.

Could you help to provide more clues, or provide a minimal reproducible setup (eg: docker)?
