The problem is that extension keeps linting files outside current project's root directory.
For example if I have
D:\projects\A (vscode cwd) ${workspaceFolder}
D:\projects\B (eslint config defined) (and a file opened in A project)

This can only be behind an option since the current behavior is intended.

Would glad too see it as an option.

• In my opinion ide may be ide for current project, not when you just open file to view it.
• While you work on project A, you might not want to fix problems in others.
• It's also weird that of course it does not respect B/.vscode/settings.json (where I configured eslint to be silent).
• Also not sure about performance, just imagining how opening single from each other project would load eslint.config and applying all rules while some (like imports resolving) cannot be accurately linted without whole project structure.
