By default the node_modules-folder is not ignored. It should be considered - to align with ESLint and Stylelint - to ignore the folder by default.

ESLint
https://eslint.org/docs/latest/use/configure/ignore

In addition to any patterns in the .eslintignore file, ESLint always follows a couple of implicit ignore rules even if the --no-ignore flag is passed. The implicit rules are as follows:

• node_modules/ is ignored.

Stylelint
https://stylelint.io/user-guide/configure/

Stylelint ignores the node_modules directory by default. However, this is overridden if ignoreFiles is set.
