Inline snapshots are not written to js files containing JSX syntax when the file is located in a subfolder

💥 Regression Report

Inline snapshots are not written to JavaScript files containing JSX syntax when the file is located in a subfolder. It works fine if the file is at the root of the project. It also works fine for TypeScript files in both root and subfolders.

Last working version

Worked up to version: 26.6.3

Stopped working in version: 27.0.0

To Reproduce

Steps to reproduce the behavior:

1. Create a React dev environment using the following packages or clone my repo.

"@babel/core": "^7.15.0",
"@babel/preset-env": "^7.15.0",
"@babel/preset-react": "^7.14.5",
"babel-jest": "^27.0.6",
"jest": "^27.0.6",
"prettier": "^2.3.2",
"react-test-renderer": "^17.0.2"

1. Create a JavaScript test file in a subfolder e.g. ./src/inline-snapshot.spec.js

import React from 'react';
import TestRenderer from 'react-test-renderer';

it('should produce inline snapshot', () => {
  const result = TestRenderer.create(<span>test</span>).toJSON();
  expect(result).toMatchInlineSnapshot();
});

1. Run the test using jest

Expected behavior

The inline snapshot should be written to the test file.

@SimenB based on the recently released changelog and the linked PRs I think that perhaps this issue has been fixed by: https://github.com/facebook/jest/pull/13150

It’s worth noting that this bug prevents you from being able to update inline snapshots in files using flow syntax - locking that entire language out of using v27 if they want to update inline snapshots without resorting to the hack above.
