Incorrect README.md link in subirectories

Summary

I believe this is the same issue reported in #3266 (closed). The link in the title for README.md residing in a subdirectory is incorrect.

Steps to reproduce

This repository demonstrates the issue: https://gitlab.com/msteinert/readme-bug

• Navigate to the subdirectory
• Note the incorrect link in the title for the README.md

The link should point to https://gitlab.com/msteinert/readme-bug/blob/master/subdirectory/README.md. Instead it points to https://gitlab.com/msteinert/readme-bug/blob/master/README.md in the root of the repository, resulting in a 404 response (as that file does not exist).

Expected behaviour

The title link for README.md in a subdirectory should point to the file in that directory.

Observed behaviour

The title link for README.md in a subdirectory points to README.md in the root of the repository.
