@SunsetTechuila Sorry for the delay. It seems like the main maintainer has stopped maintaining it for quite a while.

I can help with the review, but I never worked on this repo before today and don't know VSCode much. Could you add a bit more context to the original post so I can understand what this is doing/changing? Also, is there a relevant test that you can add?

after (the active line changes only when I press Enter):

Why doesn't the current solution work? I have no idea. VSCode APIs are poorly documented, and after some experimentation I think this is a bug

Thanks!

Could you take a look at this failure? https://github.com/editorconfig/editorconfig-vscode/actions/runs/13062880401/job/36449691603

It looks like the Windows test became flaky after this PR.
