Since v3.4.0, diagnostics within code editors have stopped working when inside of a modern yarn repository.

I have tested with both neovim and VSCode. Up to v3.3.1, diagnostics are reported as expected. Note that manual linting via the command line still works.

I believe the change would have occurred in #736 , as it is the only change brought in v3.4.0. Looking through the code, I'm not sure what exactly is the culprit, hence the issue report instead of a fix.

Here is a repo I have created in order to demonstrate the regression. The main branch uses the latest version of eslint-plugin-prettier. For ease of testing, I have provided another branch, downgrade, which uses v3.3.1 to demonstrate a working state.

If you need any more documentation or logging, please just let me know!

Thanks!
