Repro Code

The logic ingetProjectConfigFiles compares the length ofparseSettings.filePath (dirname) andparseSettings.tsconfigRootDir to stop looking for the config.

But whentsconfigRootDir is not set in the.eslintrc.js config, they can be totally different paths, for example, depending where VSCode was installed (value used fortsconfigRootDir) for tooling.

Then, it is correct to stop looking for config "only" if theparseSettings.filePath starts withtsconfigRootDir, otherwise just keep looking up to the root.

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"@typescript-eslint/<rule-name>":["error", ...<options>],},parserOptions:{project:true}};

tsconfig

{"compilerOptions": {// ...  }}

Expected Result

The config file should be found.

Actual Result

The config file is not found because it stops prematurely.
