False positive for jsx-indent in plain JS

[amneacsu]

After upgrade from 17.8.0 to 17.8.2, jsx-indent now complains for plain strings in plain JS files. I was expecting eslint-plugin-react to ignore this file, as it's not importing React or using JSX.

// somefile.js
const foo = {
  bar: 'baz1\nbaz2'
       ^ Expected indentation of 4 space characters but found 0
};

Fixed in 17.8.3.
